I haven't used GNOME 3 but it sounds like OSX's Spaces are a bit more usable at this point. This article talks about dragging icons around to move applications between spaces -- in OSX you can just drag the window itself independent of the application so you could have a Numbers spreadsheet in Space 1 and another in Space 2. It's based on the window not the application though you can statically bind certain applications to their own space if that works better. Multiple monitor support is nice too. I think I remember using that in GNOME 2 though so I'm sure 3 will support it too.

I don't find Spaces to be more usable, I find them clunky and confusing...but I have a dozen years worth of habits on Linux desktops which may be working against me. Honestly, though, I find a lot of Mac OS X and Apple interfaces clunky and confusing (and I generally have horrible things happen when I try to use them, like deleting my whole music collection when trying to use iTunes to put stuff on an iPod; iPhones also confuse the heck out of me). I've often referred to myself as "Appletarded" because I don't think I think like a normal person at this point, when it comes to interacting with technology. Apparently, many people find Mac OS X intuitive and easy to use...I find it really difficult to do anything beyond just using applications at a very basic level, and even that is often filled with frustration due to all the magic incantations you have to just know to do things (no right mouse button, so to get a context menu, you gotta know the key combo or how to use the magic mouse pad to create a right click event).

I'm basically the definitive "doesn't like Macs" user. Mac OS X is moderately better than Windows, but only by a smidgen, in my estimation, and it's certainly not a great UNIX. So, take my rants with a grain of salt.
