6k for a 4K 20" tablet with a 2 hour battery that weighs over 5 lbs with only an i5 and 2GB vram? This isn't going to be the ultimate Civ 5 machine that I've been hoping for.
Hopefully manufacturers delve into that market more and drive the price down.
Last time i was there i saw 3 or 4 of what you describe. 20 to 30in tablets with bases to use as desktops
