Android - a far superior OS. Not for nothing have Android phones 47% of the market (and according to last Saturday's FT, that will be over 50% by the start of next year). Have tried a few Android fondleslabs, great, I'd buy one, but I already have too much stuff (PC with XP, laptop with '7, Acer with Linux and Palm with something else.) Of all the OS's I use, Android has them beat hollow.
