Hi Maybe I'm just not used to it, but one annoying quirk I have found with mac keyboards (I recently bought a 20 inch iMac) is the keyboard is always giving me double letters when I type that I always have to go back and edit out. I already went to system preferences and changed sensitvity and repeat settings to the slowest. It's ridiculous in how inaccurate it is; has anyone else experienced this problem and/or have any suggestions? Just in writing this paragraph I've had to fix at least 10 times. No other keyboard has given me such fits before.
