One other thing nobody is taking into consideration is this:
Intel recently announced a few weeks/a month ago, that they're producing a low wattage cpu coming out 1Q 2013. Furthermore today I saw an article about 'limited edition' cpu's (I think the first was cloverfield, this is haswell iirc) and they'll be sub-10w power requirements. In either case, the runtime of these will be dramatically different than previous wattage cloverfields (if that is still what's going in the Surface Pro vs the limited edition haswell) so all the speculation of "omg the battery life will suck!" is completely unnecessary and most likely the negative point apple fans are trying to push.
I think ultimately w8gaming and several others have the right idea, this is the FIRST generation of the devices. Bottom line. Also, their current specs are superior to the first several generations of the Ipad and of course the android tablets. Furthermore, I believe the Surface RT and Pro beat all other Ipads hands down for the simple fact of including a USB port. I consider this a common sense feature, Apple (even under Jobs) made the mistake of trying to change the users habits instead of tailoring the product FOR the users. I'm sure Steve Jobs would have loved to see it, merely because even though I'm not an Apple fan, I always had the feeling he appreciated fine pieces of technology, a piece of art if you will, that many products have come to be.
