dude todays news confirm that Ipad has the same cortex A-8 processor overclocked at 1Ghz that apple has been calling Apple 4 processor. Because of its size i am sure they must have added components to deal with overheating.

Now your question was do we regret buying N900? N900 has already been overclocked to 1Ghz (safe till 900Mhz), same exact processor as iphone 3gs and ipad yet it takes a u-turn here. Absolutely upto you how you want to keep it unlike Apple products. I have had a blast overhauling the conversations UI. I absolutely love the device and what it offers.

I do feel i use it way too much, that in itself says how great the device is. It has pretty much replaced my laptop for internet-usage and other basic multimedia usage.
