http://tweakers.net/reviews/2199/mac-os-x-107-lion-voor-de-leeuwen.html in short: + price is right. new gestures work like a charm. encryption nice addition and easy to use. resume works well. appstore not obligated yet. solid release. - new iOS like features not too cool, launchpad not suitable for non touchscreen Macs (video review), full screen apps not very useful and mature yet, very few true new features making it feel like a minor release instead of a real OSX upgrade. Too much emphasis on new users. mission control nice but too crowded for some. they don't consider it a must-upgrade release. inconsistency for power users.
