Works fine use the free one, it does most everything you need........
I think the pinch and zoom only applies during picture viewing. Picsay is a picture based program I believe so I don't know if it will work in browsers and such. However, I hope I'm wrong.
Pinch & zoom works in the dolphin browser as well - it's in the market.
Gotta say that even though I haven't quite figured out all the dolphin settings, it works much better for me that the stock browser on my droid.
