I don't agree with all points, I've been on Mac for a while and as a designer (it's will always be based in our
daily tasks/needs) I find Mac OSX quite superior to Windows 7 in the usability/user experience, the UI is
minimal, staying out of the way but yet powerful with some features Windows 7 lack by default.
The Way the OS work with the apps is far superior too (again based in my experiences), in the same Macbook
when running OSX, I can have Photoshop CS5, Mail app, Safari, iTunes (playing), Adium, iChat and
many times, iPhoto, with the same equivalent amount of app running under Windows 7, the Macbook goes
slow to death.
In my opinion, Microsoft is slowly going after OSX UX along the years, hiding many Explorer
"advanced" features that are not very important/relevant to the general users and look the
Windows 7 "superbar", remove the background and you'll a kind of dock.
With the OSX App store to come out soon, I wouldn't be surprised to see Stardock start to develop
"apps", in fact I think it's a great move if this Store follow the success of the iOS app store.
