OK, Maybe my original words were a bit harsh... I'll revise to "A desktop can't do anything that a laptop can't, excluding the server role." But really, no one would ever use an Internet Tablet or personal sized computer to run Google's daily operations. I was thinking typical personal use stuff. Big fast RAIDs and multiple gigabit ethernet cards aren't typically things you would need in a 'personal computing' role.
Upgrading hardware, in my opinion, is almost worthless any more. About the only thing in the box that isn't obsolete in 6 months is the case and power supply anyway. Heck, my $2k laptop from 2 years ago could easily be replaced today with a much more powerful laptop for $600.

I dunno, my whole point was that eventually a small tablet PC could replace a lappy for a person to carry around for personal / office use, but at the moment is very lacking. I don't even consider my 770 to be a good web browsing device compared to a full version of Firefox. Lack of at-the-office usability (MS Office / Exchange / Outlook) hurts too. The one thing I really do love it for is scribbling notes in maemopad+, and keeping my calendar up to date. Having games in meetings @ work doesn't hurt either
