You can read the extensive preview of OSX Lion at their site. I'd say I have to agree with many of their comments and wanted to see what the rest of you power tower users thought. Full screen apps are nice but overkill for ical etc. Gesture based interface really only works with multi-touch so if you don't have a magic mouse or trackpad they won't do anything. (Which I don't, I use a Wacom tablet) Thankfully most of the default changes can be turned on/off like no app light (to let you know what is running), dashboard on it's own "space" etc. Personally I use spotlight or my dock for launching apps and I really don't get the whole iOS dashboard icon grid. Honestly I like to upgrade asap (I'm impatient) but having most of the 'features' being pointless (for me) and not knowing if Lion will break CS5, I am definitely holding off.
