Again apologies for the OT ...

My bad. If apple can develop that system, that'll be awesome. Heck, duals will be possible!

Sorry, I didn't know.

AMD was working on liquid cooled versions of their low end k6-2 and k6-3 processors some time back using very small copper tubing but i don't know what came of that

since then, the k6 series has been replaced by the more capable duron series on the low end of amd's processors

It fits nicely with Apple killing off OWCs external iDVD compatibility patch. There was no reason to unless they either had their own version ready or were about to release a Superdrive Powerbook.

Umm.. no. All that was about was making sure that if you had any thoughts about burning DVD's, you would have to spring for the higher margin machine that included an internal superdrive. Change your mind and want to burn DVD's? Go buy a new machine, or drop a thousand dollars on DVD Studio Pro. That's what killing that patch was all about.

No, that makes no sense.

The main market for 3rd party external DVD writers is for Powerbooks, the OWC one is even Titanium styled. Powerbook owners aren't going to buy a PMac just to burn DVDs, and DVD Studio Pro is expensive as hell. Apple don't stop you retro-fitting Superdrives in in towers, and iDVD will work then.

A few weeks before killing the patch, Apple killed retrofitted DVD eMacs. At the time that seemed like a way to force people to buy LCD iMacs instead. Then the Superdrive eMac was released.

I think it's a possibility anyway.

I actually found a page with liquid cooling units for pc's. The down side was the cost and the extreme attention needed when installing the insulation.

Why does this post sound like sour grapes? You wouldn't happen to work for one of the other Mac rumor sites that compete with Mac OS Rumors for street cred, now, would you?

 

[shadowfax]

every time someone starts the credibility argument, it makes me smile--because i am holding back laughter. it's barely worth getting into. granted some sites are more reliable than others, butall of them are wrong at least some of the time. none of this is guaranteed. and all of it is highly possible, in this case.

and when you start accusing people of curious affiliations, the laughs really start coming. good lord, it's just for kicks. just for kicks...sure, maybe it costs apple money, but that doesn't mean they should try and stop rumor sites. people absolutely have a right to make rumors, and be paid by companies dumb enough to be advertised on a site whose credibility they haven't thoroughly checked out.

i dunno... laugh at life. we all want new PBs... nobody is ABSOLUTELY sure, but we can reason our way into it if we want, don't you think?

daRAT,

I should have mentioned that systems using liquids such as Fluorinert for cooling can be very expensive and usually are used in research and manufacturing.

Another CPU cooling technology is the use of a cooling fan that actually creates a partial vacuum. The resulting low pressure condition drives down the temperature. Agilent is one company that makes these fans.

That was kinda my point. RUMORS people. Most of them are made up. Don't count on them as the facts MOSR is trying to pass them off as. At least this site is a little smarter, and offers something worthwhile. That's why we're here.

I don't work for any other rumor sites. I doubt the other people downing MOSR do either. Notice Arn isn't saying anything. Why would he quote someplace, then put them down? Based on personal experiance, MOSR is consistantly wrong.

Ultranoia, your name suits you. Paranoid much?

And the fact that it hurts Apple sales (and our moral) is not so good. Especially for a site that makes money from stuff involving Apple. What are they nuts? And the advertisers. Silly advertisers, don't they know nothing.

Gotta admit, people still go there, so they must be making money.

Sorry if I offended you. I shouldn't have accused you of pressing sour grapes. It's just that your criticism of MOSR seemed a bit vehement, given that we're talking about "rumor" sites, not hard news purveyors. To flatly say that MSOR has "no credibility" and that anyone who "believe that web site is a fool" sounds a bit intemperate, given the speculative nature of all these sites. (BTW, I have no connection to MOSR, other than that I read it along with this one and Thinksecret and SpyMac.) I suppose I was just trying to fathom why anyone would get so exercised over the relative worth of one rumor site over another. It baffles me, but I erred in ascribing an insider motive to you.

My point being, don't take this too seriously. Just because someone writes it, especially someone as unreliable as MOSR (we can cite specific examples if you'd like), that doesn't make it true. And I don't like the way they are presenting this stuff as fact. It's not a fact, even if it comes true. It's a rumor. They probably just guessed. They do that a lot.

I didn't take any offense (takes a lot more to offend me). Your statement just seemed kinda... odd. Was that just a joke that I didn't get, or do you really think we'd be doing that? I mean no offense, but that seems kinda, well... you know. Paranoid.

Especially when most of them just quote each other.

Edit: Where did I call anyone a fool? I wouldn't advertise on their site, but if they get hits, maybe the advertisers get results. To be honest, now that you mention it, a person would be a fool if they believed everything they heard. As you yourself pointed out, they're just rumors. I think we can all agree on that.

But yes, it does make me mad when these RUMORS are presented as facts. Then everyone gets mad because it didn't happen. You rarely see Arn doing that (and no, I don't work for this site. I'm just a fan). Hate to be a buzz kill, just don't get your hopes up too high. And try not to be too disappointed if this doesn't pan out.

I can give you numerous examples of how MOSR has p*ssed me off if you'd like. Look at some of my former posts.

And you'll notice I don't bring up the newbie status. I've been here for awhile, but my post count is fairly low.

as far as credibility goes, the two craziest rumors i heard were of an lcd imac back when lcd's were a grand each and of a mac "sphere"

as it turns out, the imac now is a half sphere and sports an lcd screen, and now on the top end, a 17" inch lcd screen

not too long before the introduction of the new imac, these rumors would have sounded completely off the wall to many people

the rumor now that i find hardest to believe is that apple will use the ibm power4 processor on the top end of the macs in the future...somehow, i just don't believe this will happen, and if it does, i can't see it happening anytime soon

another thing i don't forsee is apple having any machine scale up to 2 ghz before mid-2003, but i hope i am wrong on this one and apple starts catching up...it just seems like the pc world is still leaving us in the dust

one pc maker, i can't recall...maybe ashton digital, brags about a 2.8 ghz pentium 4 laptop coming soon...that is too crazy to believe but they printed it so they will have to eventually deliver

i would still rather have the 800 mhz tibook

daRat,

Your memory serves you correctly. I do know of a chemical called perfluorocarbon, trade name Fluorinert, that belongs to a class of heat transfer media used for cooling electronics. It does have a high dielectric strength. What you've basically described is a refrigeration cycle, which uses mechanical or heat energy to bring about a change of state in a refrigerant, which in turn removes heat from a location where it is objectionable to a location where it ain't.

Apologies to all for my OT reply to an OT post.

Your sharing of knowledge was apology enough

A lot of PC makers are releasing laptops with desktop versions of the P4 processor. So they can release the 2.8GHz machine. However, it runs hot, batterly life is horrible, etc.

It is a desktop replacement that you can carry around, not a real laptop that you can run decently off the battery.

Crippled P4s

I see Intel has just released a 2.2GHz mobile version of the Pentium 4 (http://www.theregister.co.uk/content/3/27144.html)
Sounds good only problem is, when you have battery power the speed drops to 1.2GHz. Sort of defeats the object somewhat I'd have thought. I wonder if G4/P4 laptop speed comparisons are made with battery or mains power?

Do powerbooks drop the chip speed when running off the battery?

my "old" ti400 goes 300 but i can't see the difference.

with a brand new bto upscaled liion battery on a pc laptop i saw reviewed at 2.2 ghz, the thing got only 2 hours and was unable to play dvd's all the way thru

I was at CompUSA yesterday looking at the 800MHz Ti's and negotiating on a better price. When I bought my first Mac (G4/533) they took $300 off the "sticker."

Me: You guys have to give me at least $400 off this system.

CompUSA: I don't know if we can do that.

Me: Well, in like a month the new TiBooks will be out and this system will be worth much less.

CompUSA: Let me talk to my manager. (He returns from talking with his manager) We can give you $300 off this laptop if you want to buy it today.

Me: I'll think about it. Give him my phone number so he can call me if you can take $400 off.

CompUSA: OK.

-They called me this morning and left a message. I'm about to call them back. But there's a lesson to be learned:

Don't be fooled by retailers! NEVER PAY FULL PRICE FOR ANYTHING OVER $3000.

Find out if they have proof of new models please! They will be able to see the EOL status

 

[blackpeter]

I'll see what I can weasel out of them. But I think we can take this as a clear sign that something is on the horizon for the Ti.

MacWarehouse are clearing stock too, both here and the US.

Looks promising doesn't it?

i have heard millionaires say, "never pay full price for anything"

that takes good haggling, and with my personality, if i went with that philosophy and always tried to work angles, i would take 20 years off my life

i have one strike against me...super, super high cholesterol...add hypertension or stress to that, even a little, then i am in trouble...but what does a cardiologist know about heart attacks

It used to be an option: under previous versions of the OS on older hardware you could select whether you wanted the processor to drop to a lower speed when running off battery to conserve battery life. Don't know if the option is still available under OS X on new hardware (waiting to buy a TiBook...). Of course, having the option to do so isn't the same as it being forced upon you, which is the impression I got from the article I quoted on the Pentium 4.

OS X still lets you choose a range of settings from Highest Performance to Longest Battery Life and several inbetween, or Automatic.

No forced speed drop here!
