You sure spend a good deal of time around here passing judgement on others and belittling those with differing opinions. Might be time to consider growing up.
In terms of he refresh behavior, my iPhone 4 on 4.2.1 behaves in almost the exact same way as the iPad 1 in the video. Refreshes needed quite a bit and checkerboards on fast scrolling. Of course, it has 512mb of memory. It'll be interesting to see how much that changes once I drop 4.3 onto it (waiting for unteathered jailbreak to be ready for prime time). I agree that 4.3 may be the big difference and this test is basically invalid.
Hahahaha, rolling your eyes at someone who wantonly wastes money is called "belittling"? If so, then I'm fine with that. There's a big difference between reasonable people and people with no control over their gadget spending, and there's nothing wrong with pointing that out..especially when someone flaunts this behavior as if it were appropriate.
And, since you haven't used 4.3, and I've been using it on iPhone 4 and iPad 1, I again repeat, 4.3 is the key. Best midterm Apple software update, ever.
