Personally, I've alternated between Thinkpads and Powerbooks/Macbooks for a number of years. It is very immature when people blindly make statements on anything.
Try everything, be open to everything. Up to 1 years ago, I was very happy with Apple. At this point, with the messy Lion situation and the aluminium madness, I find myself going Thinkpad again. Still no viable replacement for the Air though, the thing is unique.
I recon Apple will reach its peak in three-four years time, at which point they'll go the Microsoft way. I suppose that's gonna happen when Macs/iPhones/iPods become the "cock's" gadget.
Lots of Apple's appeal is just based on looks (likewise for Thinkpad). Being a designer, I can appreciate it (looks are extremely important in everything).
Otherwise, these days, windows or OSX, OSses are working fine fo 99% of people.
