I think in a lot of ways it trumps the ipad [size, weight, power,tech]
but it doesn't have the vast collection of apps that Apple has. [or the name backing.]
I'm personally not ready for tablets and I don't think they're useful for the common consumer. Many people that I know with ipads haven't used them in weeks since purchase. I can only understand the need in the medical field and for really bored people with money to blow. I think the tablet craze will fade soon and pick up heavily in 5 more years.
That said...if I HAD to buy one....I'd go Android.
