I didn't use Spaces before Lion. It's still not perfect but I like it better now with Mission Control. The full screen behaviour is annoying. What if I want to go full screen on a secondary display? Huge oversight and who knows when they'll fix it. (fwiw The reasoning is that if there's only one app the menu bar should be above it or something so you don't have to move your mouse to the second display to show the menu bar. I think it's a lame reason since people w/ multiple displays are typically not grandma types that get confused about such things.) Maybe old configurations don't mess things up. I had nothing but great experiences with Migration Assistant and upgrades since I started using Macs in 2005 until Lion, even through the PPC-Intel transition. I had a problem with my upgraded Lion machine though, it no longer connected to my Windows 7 machine's SMB shared volume. After doing a fresh install I was able to connect again and I had tried connecting from 10.6 so I know Lion was at fault. That's the only issue I had but it does lend some credibility to the fact that old configurations can be problematic, in my eyes.
