Hi guys, I have purchased a logitech bluetooth keyboard with my sony tablet because i was planning do a fair amunt of writing with it. But the keyboard is so sluggish in its response time that it's essentially unusable. Anyone have an idea as to why that could be? If bluetooth is the problem, can i hook up a keyboard via usb? I should also note that bluetooth kb operation sometimes seems to knock out wifi, which is quite annoying. Thank, O.h.
