The SurfacePro is nothing but a laptop with a touch screen, no more, no less.
those battery times are pathetic and are in line with my $350 i3 powered Acer laptop on its very best days of minimal use.
When all the dust settles, the SurfaceRT and Pro will be in the rear view mirror to all these others out there from Apple and android powered stuff.
They may be in the rear view mirror, but it will be to other Core iX machines running Windows. The bottom line is that for business, a tablet needs to be running a real OS, and needs a real processor. You just can't have 8-10 hour run-time with that horsepower in a tablet form factor.
Unlike the iPad, the Surface Pro isn't for playing Angry Birds and watching YouTube videos. It's a business machine that does things the iPad can't. The iPad is not the competition.
It's also not a laptop, so that's also a terrible comparison.
