I think you guys are missing the point..
Windows 8 + Haswell + custom tuned hardware = Surface Pro 2
This will dominate anything android// ios..
Real windows, real pirated software, real photoshop, real autocad, real maya, REAL freaking games, NO MORE VIDEO CONVERSION, MPC-HC, MADVR for anime, OMG...
all this and it will probably have 10hrs of battery life, since microsoft will have close hardware access in this thing to optimize power use.
