I had never played with a Mac before getting one, not even in the Apple shop. I did have a Dell XPS, nice laptop, lots of power...... just got fed up with programes chugging, USB kept stopping, got very hot and the fan was very noisy. Just wanted a change.
Also how surprised was I at the OS upgrade to Lion for £20 ....... not £200 odd for Win7
Apple seem to have a more innovative approach to doing things... like the touchpad 1,2,3, finger swipes - Just brilliant
