Just thought I'd share my experiences with a gyro mouse/keyboard that I recently purchased in case anybody else wanted to take a look http://www.amazon.co.uk/2-4GHz-Sensing-Wireless-Keyboard-Android/dp/B008S73V8A
It's great! The keys are nice and "clicky", and don't leave you with that "have I pressed it, or haven't I" feeling. The gyro mouse part works well also - compared to the GO Plus Gyration Air Mouse, which I think is ridiculously expensive for what it is, it is almost as good (in terms of cursor movement). When you press the button to stop the cursor from moving there is a _slight_ delay, but to be honest I don't use that button now that I am used to it.
Negatives - some might consider the piano black finish to be a bit cheap, but personally I don't mind (speaks volumes about me!) - it does come in white though. Shift needs to be held down for the function keys. And it isn't rechargeable, the x3 AAA batteries need to be physically replaced. That said I've been using it continuously for a month and haven't had to replace the batteries yet, so it must be fairly good on juice.
Bottom line is that I am going to buy another.
