I got the Slate7. First, there is no working driver for the accelerometer. If someon could dig out a W8 driver from the /BULD tablet it would be great. Second, tap and hold for context menu is very unreliable with finger. Works fine with pen.
I had the tap and hold issue with the DP but it's much better with the CP on the build tablet. I wonder if there are more driver/hardware differences than you'd think between these tablets. It also makes you wonder if the Windows devs are using the build tablet as the benchmark for "good enough". I'm sure at some point they'll run everything through some certification program.
