HP Omni 10 available for $399 at Microsoft Stores and $349 @ Office Depot.
Thats a 10'' tablet running full Windows 8.1 + 1920x1200 screen. It's based on the Z3770, fastest Bay Trail-T chip right now (20-30% faster than ASUS T100's Z3740).
I'm evaluating a couple of cheapo Chinese bay trail tablets today. One with a Z3740D (1.33Ghz), one with Z3770 (1.46Ghz), and one with an N2910 (1.6Ghz), all quad core, 2GB, 10.1", win8. Z's with Samsung eMMC, the N with BiWin M.2 SATA. All designed for ~2.2W TDP (of SDP in the case of the N2910)
