DigitalFrog: I’ve had that very same problem, and here’s how I solved it. I have a 1GB SanDisk I keep loaded up with all the letters, and when my keyboard starts to run low, I plug in the SD and charge it back up. Never have to worry about running out, and when My SD starts running low, I just go to the Alphabet Store on the internet and re-charge it for a nominal fee. Works great. Hope this helps.
