Overall it's nice, but there are some REALLY FUCKING bad design choices for the sake of customization. For instance, on XP, I would made My Computer a taskbar at the top of my screen. Win7 prohibits taskbars other than the main one. Also, I'd like to have some folder shortcuts, but any time I place those shortcuts on the start bar, it only opens Libraries. I DON'T WANT FUCKING LIBRARIES! I PUT MY SHIT IN FOLDERS LIKE ANY ORGANIZED PERSON DOES!!
Also, they renamed a bunch of functions in the Control Panel, so Add/Remove Programs is no longer at the top. If I want to view my network connections, I have to page through several windows instead of just placing a shortcut on the side of my Start Menu. Every time I use the Open dialogue, it defaults Libraries and I can't use the scroll wheel to shift down to where I want to go until I click something on the side pane which opens it up. Pain Pain PAIN one after another.
But yeah, overall I like it and wouldn't consider going back to XP.
