Thank you Jasoco!
Thank you for the videos Jasoco! (I really like the music in them by the way, ignore what others say, its nice to see others who like movie soundtracks).
Some of the features I am excited about is:
1. Mission Control. I am a multitask monster who uses a lot of spaces and such this is a nice upgrade from Expose.
2. Group in Finder. This is a huge convenience even if it is just small. I generate a ton of files in the work I do and this is a nice feature to help me quickly group everything. (I know people will say "But can't you make a folder before hand and save everything in it??" Well, we all work differently and sometimes I don't know where the files I make will be grouped.)
3. Versions. This is great too! This would be very nice in XCode where sometimes I will have large sections of code commented incase something doesn't work right I can copy it back in. With versions, I wouldn't have to worry about that.
I'm really excited about this and I really enjoyed the videos. Too bad I have to wait until programs like Maya, Photoshop, Houdini, ZBrush, Corel Painter, Unity, and a few others are compatible with Lion before upgrading

(Although I can upgrade my air if I really want too...)
