Apps and games for android especially free one are growing like mushroom now..
Everyday have latest apps and games or updates for current one..
I'm using AppStore and SlideMe 3.4 to get all of them easily..
Currently using HTC Tattoo and it satisfy me enough to get into smartphone criteria rather than my former Jet.. 
Yes, Android has antivirus for mobile.. free or paid version(normal right?).. but free version is good enough to prevent harmful 3rd party apps and games(not all)..

My friend had a view on my Tattoo before and he was surprised with lot of apps and games that i had!! 
But, if Tattoo is using capacitive touchscreen... i'll satisfy enough.. But i don't care about it at all.. Because it's my 1st smartphone and it's android..
Don't worry.. As some says that Eclair version is on coming.. with high end features.. maybe android can beat iPhone MacOs one day??
Who know.. Android is still new in this area..
