Android is very fastest growing os there are lot of apps available in  play store
Motorola,micromax,samsung,lg,lavaxolo,sony,karbon,etc all mobile built with android lot of development in a short time
Nowadays there are many highend motion sensor games are developed frontline commando , dday ,gta vice city,nfs mostwanted ,virtual tennis, moderncombat 4, spiderman , lot of time pass feels great to play this kind of games with motion sensor
I strongly recommend android  ...........
