Home folders can be moved entirely............ but only if you create a custom install image and set the mount point for it in an auto answer script. Apparently you can symlink the Users folder, but on a live system I don't think I'd fancy my chances with that one ;)
Quite why MS can't just give an "Advanced" option during installation, I will never know. I would dearly love to be able to say "Stick Hom... sorry Users on the D: drive please, thanks". I totally agree with you though, it shouldn't take 600+ clicks to just move your folders to a place outside your OS partition.
Re: Backup - you also forgot with Backup, if you want to backup to a NAS or network server you can only backup to a machine running Windows 7!!!!! *arrrrgh* So it's pointless.
That said, Windows 7 is OK, but it does have lots of inconsistencies and more than a few rough edges (Control Panel especially, fourth version of it seems like MS can't decide how it should work, hint - leave it as applets that open in a new window and have done with it!).
@AC Still problems with Windows 7: re the taskbar/superbar thing, travesty/farce. I see you've struggled much like I did at first. You have likely tried to add shortcut icons and pin them; which is wrong! You need to pin the RUNNING program, otherwise it will reappear all over. No, I don't know why it is that retarded - but it is. So if you pin the running programs you can then drag them up and down and the position will be remembered with any new apps being thrown at the end. Hope that helps you a bit - it really, REALLY annoyed the hell out of me!
