No; no manufacturer has announced one yet. But do give it some thought – a 7-inch tablet with a hardware QWERTY keyboard would just make for some improved usability. In my opinion, it would move tablets closer to netbook functionality.
Yes; the display size will be reduced a bit, but that compromise won’t be bad. users would still have a large display combined with a tactile keyboard.
Then throw in a full USB port please, and we are good. Which of the manufacturers will make my day and get something like this into the market?
