I upgraded a couple of weeks and this sleep, smart operating system is the best in the business. Much better than the baffling 8.0 or luddite 7.0, it is a helluva easy system, a pleasure to negotiate and simple as 1.2.3. I have never had a Mac but I would be shocked if it is as good as this at getting you where you want to go. A personal favorite is the “Task View”. A great way to use your computer and if you have 8.0 the upgrade is free.
