Disclaimer: was running GM for a few weeks. Love: * Never been a Spaces user, neither do I use Exposé but I found myself using Mission Control more and more. It feels very natural to my workflow possibly because I hate having an empty spaces around and partly due to gestures. * Full screen apps is awesome, especially if you use web apps. Currently I created a new Safari window in fullscreen running IRCCloud, I could "peek" that window simply by three-fingers swiping to the right to see if there's any activities in channel I'm on (but not switch to it). I think more (desktop) apps should utilize this. Put some activities on left and right side of the window to allow peeking without leaving the current desktop. * I thought scrolling was stupid at first, but with Trackpad and a mindset of "control the content, not widget", it kind of make sense. * Mail.app is a bless for non-Gmail IMAP user like me. It has almost everything I want from a Mail client. My only complaint is that it lacks proper email address aliasing support. * FileVault 2 no longer randomly eats up my data and transparent to all applications due to the fact it's now disk-level encryption rather than an encrypted disk image. Never did a benchmark, but the performance impact doesn't seems noticeable. * 256 COLORS SUPPORT IN TERMINAL. Dislike: * "New window" effect, it adds a lot of delay and adds nothing in terms of usability. Unsure: * I want to like Versions, but couldn't get myself to like it. There's this one time when I open an existing file, accidentally delete half of it, close the window to try to restore its previous state but TextEdit simply overwrite the file on exit.
