I read in one of the various 'taking the ipad apart to see what's
inside' articles that the iPad in fact had 512MB of RAM. Still not a
massive amount, but I'd imagine you won't be running FInal Cut Pro on
it so...

To be fair, for 'everyday' use, there's absolutely no excuse for not
being able to run on 256MB of RAM - we're just used to everything being
bloated to the extreme.

I swear this MacBook Air is no quicker at normal office / browsing type
tasks than my Tonkabook.

That turned out to be a misinterpretation of part numbers. There are
two 1Gbit chips in there, so 256meg.

The shipping iPads have 256MB of ram acording to iFixit. It was
incorrectly assumed they would be 512 in the early guesses.

Even with VM (which I suspect *will* have to be enabled to avoid
surprises that are more harmful than the thing slowing down)
multitasking will at least force you to handhold the system (quitting
apps in the background you aren't needing anymore, decide if you want to
really quit or just background the app you're leaving and so on). I just
hope Apple will make that straight and easy.
