I will not be transitioning to Longhorn, no matter how many features are added. It incorporates too much 'DRM' (I'll manage my own rights, thank you) and is looking to be excessively insecure (WinFS, Longhorn's NTFS replacement, is a combination of NTFS and an MS-SQL server - one of Microsoft's most insecure products on top of what is supposed to keep my data safe? NO!!!!)
Microsoft also has me extremely pissed over the delay of Service pack 2 for WinXP - there's NO fvcking reason that I should have to download half a gig of updates for every new machine when they could just be mature and release the damn package instead of releasing it a year late just so they can have more 'feature enhancements' in it. Service packs are supposed to fix bugs - not add features. That's just an added bonus, that, quite frankly, I don't care about.
