There may not be the crazy selection like on the iPhone (former iPhone user as well), but it's not bad. In all honesty, I really only played 5-6 games on the iPhone regularly. The rest of the- ummm... lots that I bought went unused after the initial fun wore off.
I've been pleasantly surprised how good some Android games are. I think Radiant is a great, well polished arcade shooter. Space Physics is an amazing puzzle/logic game. Then there are newer titles like Totemo and What the Doodle, that are looking very promising.
