This is obviously just my feeling. But this more "iOS" based OS is better suited to MacBooks. Why would an iMac user, especially a 27in user need full screen apps? Yes, on an MBA I'm sure it's very useful but not for an iMac. Expose and Spaces were fine the way they were in SL. Launchpad again is better suited to Notebook users. On the iMac, a Mouse click on the apps folder in the dock does the same thing as LP. I can see the benefit for Notebook users in using a gesture to open LP alright, but for Desktop users it's not really needed. You wonder should Apple have made two versions, one more geared to Desktops which would have a very subtle upgrade of SL with options to turn off any of the superfluous gimmicks you don't want and go back to normal spaces etc and then leave Lion as is for Notebook users? Lion seems to be as buggy as hell judging by the posts on this site and others. I got my iMac last week and will not use the redemption key to upgrade to Lion yet, certainly until a lot of the bugs are sorted. I use a trackpad as well and the gestures are perfect for SL on the iMac imho.
