Shudder. I helped my girlfriend's parents get a new machine, and it came with XP - no way around it. I wanted them to get an iMac, but they really wanted a PC...
The coolest part of this computer is no doubt the screen. It's a Samsung SyncMaster 171v, a 17" viewable LCD, and it's amazing. Crisp image, giant screen surface, 1280x1024, contrast ratio 400:1. And only $400, too (after $150 mail-in rebate)!
So my first real experience with XP (yes, I had been lucky so far :) Their machine has a P4 2.4GHz, 512MB RAM, and a 60GB 7200rpm hdd. You would expect it to fly. Well, not really. XP is slow. I'm currently looking at a tweaking guide, maybe that will help.
What blew me away, though, was when I selected 'Windows update', giving me no less than 26 'Critical updates and service packs', and another 20 or so less critical fixes. Wasn't XP supposed to be Redmont's safest OS ever? Yeah, right.
What a piece of crap.
