This is propably right, but I don't know any Linux GUI:s that would beat the Windows GUI in usability
This is personal preference, Im sure Linux has a lot more in regards to configuring the appearance and whatnot.
But I couldn't even get copypaste to work between all programs, in Windows it works almost everytime.
Oh and I use Windows 2000 look in XP, I just like the clean industrial style look, not any fancy graphics
I also have disabled all extra functionalities in folders, they just get in the way.
That's the point, with Wine you can run the Windows applications with their UI's. Unless you are referring to the desktop environment, I don't think the Windows environment is excessively usable. The start menu is the most evil invention ever. It's the opposite of organisation. I'll take Gnome which automatically categorises my applications and configuration options by usage class over the start menu + control panel dumping ground every day of the week.
I suppose this is the blub paradox applied to UI's though. The Windows UI is god awful, it's organisation metaphor is throwing everything on the floor so you know where it is. That's what everyone is used to though, I suppose if you were punched in the face every hour for 20 years you might find peace difficult.
As for cut and paste. Never had a problem with it recently (used to be a serious problem), then again I tend to use the middle click buffer of the X-Server (select to copy, middle click to paste). Nice having multiple clipboards with different key bindings.
