Only 2 months? Yikes. Mine (2nd rev) lasts 6 months with moderately heavy usage. Has battery consumption gone up with the newer revisions? Guess they never really got it working to spec since it's supposed to flash "LO BATT" or something like that in the LCD according to the manual. Mine always starts behaving erratically before that and I've never seen the "LO BATT" message.
