[citation][nom]therogerwilco[/nom]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.[/citation]
Colver Trail is an Atom SoC, containing 2 Saltwell cores. Their architecture is different from architectures like Sandy/Ivy/Haswell, it's a derivative of the Core architecture (Conroe/Penryn), but still not the same.
What you remember are low powered Ivy Bridge parts, which were sub-13w CPUs. The low powered i5 is likely the one in the surface pro. only the pentium was sub-10w in that slide.
While the Tegra 3 in the Surface RT is underpowered for the purpose, and hence inferior to the A5X in the iPad 4, the Pro has a Core i5 which is obviously superior to the A5X SoC.
Haswell might hit 8w and compete with the ARM Coretex A15 in terms of power, i expect performance to bu much greater.
