I never felt much of a change when I switched from PC to Mac, Macbook Pro . You might get few weeks to get the feel of the whole thing if you are switcher. Its infact easier on the interface but I suggest you get a
keyboard & a mighty mouse as I personally don't like MBP keyboard for designing and other works that needs much time, but thats the case with any laptop.
Yes, try out MBP at the apple store .
