Yes, 1U != 1 inch ... nevermind that most kU form factor machines (considering that they are MUCH longer than a powerbook) have a series of fans that sit vertically in the center and push air around the box and out the back, you can't fit that in a laptop form factor.
I will reiterate what apple has already said: NO G5 POWERBOOKS FOR SOME TIME!! Give it up already!

Buuzzzzzzzzzzzz!!! wrong
...and imagine having pieces of your file corrupted or inaccessible because someone turned his computer off for the weekend... 😡
Xsan uses a central Fibre Channel disk system (Xserve RAID) that is shared by more-or-less diskless clients. You need a $500 FC card for each system on the Xsan, and a FC switch to interconnect them. (about $6000 for an 8-port switch (http://shopper.cnet.com/SANbox2_8_-_switch_-_8_ports/4014-6432_9-30626852.html))

I wonder when PCI Express will arrive ?
I wonder when XServe will get better I/O capabilities - the two 100 MHz PCI-X slots on the XServe are getting pretty long in the tooth...
The Xserve has a single theoretical 800 MBps I/O bus (or 1GBps if you only have one card), while Intel is now pushing PCI Express on the servers and workstations (the Dell 1850 1U dual 64-bit Xeon server has 6000 MBps PCI Express I/O (one 4GBps and one 2GBps) http://www1.us.dell.com/content/pro...s=555&l=en&s=biz&~page=1&~tab=specstab#tabtop, the HPaq DL360 1U dual 64-bit Xeon has 8000MBps (two 4GBps))
Some server I/O needs can no longer be met by PCI-X - a single InfiniBand or 10GbE card needs more bandwidth than 133 MHz PCI-X can deliver. Multiport 2 Gbps FC cards can also eat a PCI-X.

So you are saying if I type letters I am OK with a G4 or even an Mac Plus for that matter. But if I am doing video work and 3D design I probably could use a G5. I guess it is hard to define regular use. I have a Dual 1 GHz G4 Powermac and a Dual G5 Powermac 2 GHz and I even appreciate the difference in small things like navigating the finder. When working with multiple tracks in Final Cut Pro I appreciate it that much more.

I guess that the space for it to fit is isn't so much the problem as it is space for air to travel around is. However it seems to me that the 17 inch powerbook probably has a lot of potential dead air space. Of course Apple says not for some time or else they would kill current PowerBook sales.
What the rumor tells me is that IBM is getting good yields on the 2.3 gig G5. This, for me, opens up the chance that the PM range will also get a speed bump, with the 2.0 at the bottom, then the 2.3 and then 2.?, leaving the 1.6 and 1.8 for the iMac range - for now. It might also open up the eMac for a 1.6 before too long.
As for the G5 PB, it will be released when it is ready - meaning when Apple is satisfied with the various bits that will be critical, like cooling and battery life. I assume that there are a lot of prototypes that have been tested over the last 2 years and Apple just hasn't been satisfied. I also assume that they are working very hard with IBM to get a G5 PB on the market as soon as possible. I decided in April, when the new G4 PBs were announced, to update my old 667 PB. I wanted the power improvement for business trips and felt that I could get a good price for it when the G5 PB was announced and the initial dust settled.

Yes it does.MacBandit said:
!= means NOT EQUAL in C, C++, Java, Javascript....
He could have also used:
<> (basic, VB, VBScript, etc...)
I just wanted to be a sm@rt@$$.

- Won't the Dual-Core G4 fix that FSB problem?
- Any new info on the FreeScale Dual-Core G4?
stop this powerbook idiocy
First of all, the XSAN system is set up to run off of XRAID, which apple (and all other raid makers) ship with redundant power supplies, controller cards, and disks to prevent drive crashes from bringing down a system and also feature cell phone/email/pager/big flashing network alert systems that are automated at the hint of any problem. While none of these are foolproof, they do add up to a system that, when properly set up and administered, is infinitely more reliable than any hard disk the average consumer has ever used. There's data security built in that works fairly well along with a lot of software administration.
More importantly the XSAN is designed to relay everything across a fibre channel hub that moves MUCH faster than Gbit ethernet and is only meant to serve high end systems where, when you drop 2x$13,000 for two raid arrays plus $4000 for an xserve plus $4000 for a switch plus $5000 in backup parts and another $14,000 for a tape backup system you don't really need to worry about the tiny expense of buying a $500 card for each G5 you hook up to it. Not to mention the fact that you have a standards-compliant technology as opposed to 10Gbit, which still hasn't been finalized and won't be for a few years yet.
As for the PCIExtreme addition, realize that you've got a million other drive limitations, such as ATA only running at 150MBps, plus the channel limitations of fibre and ethernet, that are much more limiting than your PCI bus, so while I'd like to see apple make the change I think it's a little bit less pressing than simple processing power and room for 16 gigs of RAM...
