Snowy_River said:Wow, I can remember when 1GB was the max for ANY computer. For that matter, I can remember when 1GB was a pipe dream. (I remember getting excited about being able to afford a 4MB RAM card for my computer!) Right now 2GB is the top end for a number of computers. I don't see that limitation as being that significant an issue.
You can upgrade the hard drive, by replacing it. True, there isn't another slot for an internal, but you can always add externals with relative ease. Again, I don't see this as a significant limitation.
Optical drive? You certainly can replace the optical drive. Kits have been out for this configuration for some time. While, right now, if the optical drive on an iMac went bad, they'd be smart to have Apple replace it under warranty, once they start getting older, I'm sure we'll see more kits aimed specifically at the Core iMacs. While it's true that it's not as easy as changing an optical drive on a tower, it is still possible. So let's not talk about the death of the optical drive killing the computer, shall we? Hmm?
Now, there are plenty of single components that you could point to that would kill the computer. All of them are on the main logic board. But, as someone else pointed out, killing the main logic board of any computer would kill the whole computer.
And, of course I was acknowledging that there were limitations like the lack of PCI slots in the iMac. I was just arguing that saying the HD and the RAM weren't upgradeable wasn't really accurate.
2gig max on high end computer these days..... Umm no not the case. Try my computer was mid high 2 years ago and it max ram is 3gigs. My roommate computer which is about 6 months newer than mine and was built to about the same mid high at the time max is 4gigs.
Now I dont rememeber when 4megs of ram was a lot. but i do rememeber when 16megs was consider a lot of ram. I thinking with in a year 2 gigs will be near the standard ammount people will want to be running. 2 years ago 512 megs was it and 1 gig was recomended. Now 1gig seems to be the least amount you run and 2gigs is starting to come up more and more and recomendations. Not like 1gig where it about the least you want to run any more.
So give it a year and 2 gigs will be the where 1 gig is now. The standard recomended ammount to run in a computer. 1gig being the min. 512 for a crawl. right now it 1gig recomended. 512 beign the min and 256 for a crawl.
Also extranl harddrive are also slower than an inteneral hard drive. No really way around that issue. Plus things dont look at clean when you start running extranl devices. I think a 2nd intenal is good. it a lot easier to have that as a primary storage location that it is to use an extranl for it.
As for a single compontined in a iMac that will kill it that doesnt effect the tower system is the monitor going bad. instead of paying a few 100 to replace it it almost cheaper to just buy a new computer than pay apple cost of replacing it and repair.
Also the lack of being able to replace the GPU card is a big thing that is limiting the iMac. With more and more software moving over and using the GPU it seems to be the thing that is pushing replacements. In and iMac if the GPU fails that means new logic board. In a PC tower or something with a removeible card it means just a new card. In my PC tower the graphic card is hitting limitions and I am worried about it failing (cooling fan on it is starting to fail). Now in a iMac that failure would translate into a very costly repair. In my PC tower it going to cost me 150 bucks to buy a much better card and as a bonus extend the useble lifespan of the computer at least another year.
Plus you got the entire lack of ablitlity to add PCI cards to the iMac. Run out of USB ports/fireports that can be an issue. You can add a hub to your sytem but that slow down the ports some. You cannt add more bandwith to them. But with a PCI card you can easily add more parts or upgrades.
