First and foremost, DIMENSIONS. About 8" of screen, but extremely thin bezel, so about the same size as my current Nook Color [Running ICS, so stop snickering].
Glass smudging, you say? No, because it will use the non-smudging self-cleaning glass developed by MIT. Processor, any high-end current, Tegra 3, Snapdragon,
Quad-Core Exynos, with 2GB's RAM, Retina Display nice but not an absolute requirement. Battery life is extremely important - I'll take a little more weight for whatever that means to get at least 10 hours running, 12 preferred. Standard micro-ports, particularly charging, NO proprietary ports! External keyboard as an extra cost option. OS would be pure ICS, rootable, and at this point in time, Apex 1.1 launcher. Wi-fi capable, GPS (without carrier), bluetooth. Capable of micro SD of at least up to 32GB. 128GB micro SSD as an option! Oh... did I mention my $399 list price point?
