Might as well use this forum for it's intended purpose. If I started this in the Pub, there'd be all sorts of problems with people yelling "ZOMG VISTA SUX!" and "STFU N()()|3! VISTA IS TEH ****1!!". All I want is an answer to a simple question:
What do you like/dislike about Vista?
Personally, I'd love to see that new "3D window tabbing" removed. It's just a pretty form of Alt-Tab, and I don't see a point. One of my biggest complaints about OSX is the "Hey, you move the mouse here, and all your windows scrunch up and hide until you click one of them." You don't even have to click for it to happen.
I'd like to see it replaced by something like Linux's Multi-desktop feature. Got a media player running in the background, cluttering up your task bar/Alt-Tab menu? Throw it onto desktop 3 and have it out of your way. Running the FreeSpace Open Installer, and waiting for it to download all that is FreeSpace? Put it on desktop 4, let it do it's thing, and continue surfing the web on desktop 1. I personally feel it successfully does what the 3D select claims to be able to do: Reduce the time spent trying to navigate between windows. By allowing you to move windows you don't need to look at often onto other desktops, it allows you to concentrate on the important windows, without having to Alt-Tab past your media player, bit torrent client, download manager, etc. Best of all, it's unobtrusive. Down in it's little corner, it takes up about as much space as one desktop icon.
