my thoughts:
ilife 2011- incremental improvements, all look like full screen ipad apps now, imovie looks great as always. where was iwork 2011? guess im going to use office 2011 for a while now.
facetime for mac - it was going to happen eventually, but why not build it into ichat?
osx lion - mission control is a "cute" name, but its really just expose with spaces and dashboard built in (which is the point). i guess people didnt utilize dashboard enough via the dock or keyboard. mac app store is expected, and it'll be the best place for regular people to get apps, but for power users, the traditional way will still be the best method. launchpad = the new homescreen for the app store. looks interesting, but i certainly wont be using it. i hope there are options to not use it at all. also, the traffic lights were horizontal unlike itunes 10 - i had to edit a file to put them back in. no new interface enhancements? must still be too early to show off anything else.
mba - 11.6" is model is surprising. im glad they got it down to the $999 price point. this might take away from the high end ipad sales (32GB/64GB wifi and 3G). $100 for the 4GB and 1.6ghz upgrade are no brainers. 13" gets a much needed boost to 1440x900, along with 2 usb and sd card reader, and i wouldnt be surprised to see this go to the 13" mbp later on. usb osx restore drive is a nice touch, and no backlit keyboard on both models anymore! oh well...
mbp - silent updates, but the high end 15" and 17" now have the option to go to 2.8ghz core i7 (thankfully optional, so my computer doesnt feel outdated already).
