You couldn't use the keyboard before?
Don't know if he had the same fun I had during his setup, like I did on my Mac Air... cntrl+(something)+spacebar to enter to get thru setting it up. Once it was setup, everything acts almost same as a Windows based box.
The one thing I found different is the Delete key. On a Windows based box, you place the cursor behind the character to delete, on Apple it's before.
I turned the Voice Over on for a whole 2 minutes... GAWD! That function became so annoying... even my wife was screaming for me to turn it off... LOL!!!!
So far I really like the little Mac Air... small and light... easy to pack. Not so thrilled with my iPhone compared to the Droid X I had.
