You can replace all of the stuff at the bottom with Launcher Pro. I don't recall if you can with the default launcher.
You can't, and we don't even know if his default launcher is THE default launcher. I admit that this is a problem with Android.
And you can change things around in the bottom toolbar with LauncherPro, but I like how Zeam does it more. Zeam is nice and simple, and I think it runs faster.
What keyboard are you using ? I tried swype for a few minutes and switched to the stock one. It works ok but I hit the wrong letter a lot. It seems like I need to hit the letter to the left of where it is.
Like with the browser, I can't be certain you have the actual stock Android keyboard or something the manufacturer put on there, but I suspect it's probably the standard one.
My favorite is
Swiftkey (
free demo available). I just love it. I've discussed this in the other thread, so go search for it here.
