so i just recieved my keyboard and it seems great and all except the lag from when a key is pressed and when the letter appears on screen. is this normal?? or did i recieve a defective unit, maybe bad batteries? the lag isnt terribly bad, but its still pretty noticeble, probably about a second worth of delay.

I've noticed this, too. I have a Universal Bluetooth Keyboard, and there is definitely some lag time between when I type and when it displays on the screen. Also, randomly, I've noticed that it'll occasionally type duplicate characters of whatever key I'm pressing, almost as if I'm holding the key down too long. I suspect there's something goofy in the way the Bluetooth is configured. I think there has been a bug report submitted regarding Bluetooth not actually attaining the speeds it's supposed to be capable of, maybe this is related.
