I don't see how this UI decision — a screen of pages vs. a row of tabs – could be related to a hardware limitation. All other things remaining the same, why couldn't the switcher look like tabs instead of pages? Page caching is the real issue, but I think this could also be addressed by software if Apple decided to. Of all the things that could be considered deal breakers for the iPad, this is among the least of them.
