[citation][nom]BringMeAnother[/nom]I'm really interested in this, but I can't shake the feeling that it will be made completely obsolete 5 month later with the release of the Haswell CPUs which, if more efficient, will allow longer battery life with less weight.[/citation]
Haswell tablets won't happen until much later this year, a Haswell Surface pro 2, if it happens, will likely be released just before the holidays 2013. this is because the Haswell chips released in June will be the laptop and desktop models, the ultra low voltage models ideal for tablet construction are typically last to come as they usually come out after Intel has had time to refine and tune each process.
That said, ultra low voltage haswell chips will definately be much more power efficient than Ivy, and will likely render this gen of surface devices very obsolete as they'll probably have a nice 8-10hr battery life like any half decent tablet should
