The iPad's virtual keyboard isn't the easiest to use but with time, I've gotten used to it. I am writing this post on the iPad even now. And I think it's easier to type on the iPhone than on the iPad.
The Android tablets need to be able allow user a measure of productivity and that means a decent virtual keyboard. From my experiences, the keyboard on the Android so far hasn't been anything to write home about.
But perhaps there is hope. LG CEO has said that its tablets will be productive than the iPad. So we'll see.
