Well I can't think of any other device you could possibly need, but how about a little something to pamper your keyboard with? http://i01.i.aliimg.com/wsphoto/v1/602007701/Free-Shipping-Magic-High-Tech-Cleaning-font-b-Keyboard-b-font-New-Cyber-font-b-Computer.jpg
Looks pretty cool - and effective! I'd definitely get one to keep my state-of-the-art keyboard clean
(For my current $10 keyboard I'll just stick to the upside down cleaning method though).
