exactly, I'm sick of the "but XP gets the job done"-attitude. Yes, there's no killer feature, that would absolutely demand an upgrade, but all the minor changes and usability improvements add up. I'm kinda annoyed that I have to use a XP machine at work, since I've been spoiled by W7 beta at home for a while now.
The problem is that most people just see it as another ~$100 they'll have to spend to upgrade, and that isn't worth it to most.
I think it's worth the upgrade, but 90% of my family doesn't and I'll need to upgrade them with a pirated version once it's released + cracked.
Granted, most of those features were added in Vista, but Windows 7 actually runs quite decent on older hardware, something Vista wasn't exactly acclaimed for doing.
Windows 7 also includes lots of features which are handy for portable machines like laptops. Bitlocker anyone? You also have transparent, automatic VPN back into your company's domain, either trough native IPv6 or tunneled connections. In either case IPSec is used to secure communication. In effect, the windows domain model just got network transparent. That's a pretty neat thing in itself.
Again, some things came with Vista, but Windows 7 delivers it all in a much more appealing package.
I'll shut up before I sound like a Microsoft market-droid, but to say Windows 7 adds no features which would make an upgrade worthwhile in the corporate environment is either disingenuous or misinformed.
