my beloved girlfriend gave me an Apple Wireless Bluetooth mouse for my birthday, what a gal, she knows my tastes too well. anyways i'm using it with my G4 powerbook, and i love it, but i travel alot as an electronic musician and was wondering what kind of battery life i can expect? i have a rechargable AA battery kit from radioshack and i'd like to know if i need to bring that with me every month to europe? or will the batteries last a good month to two months at a time? also, a mini-review.... i love this mouse, i really like the weight of it. i have to use a mouse on the stage when i am performing to do a few specific tasks in the Ableton Live 3.0 application, stuff like dragging audio loops to another channel after they've been used in a performance (not very fun to do with the touchpad). I've been using the Logitech MX700, and all the features and extra buttons on it are great, but its wireless applications are limited in that it needs to be plugged into USB, and also into a power outlet to charge. The self charging of the MX700 is great and i recommend it for desktop mac's. I occasionally had the mouse jet off on me, and i suffice it to a buggy Logitech OS X driver (it seems there is one driver for all logitech mouses. enough of the logitech, back to the Apple mouse... there is a tension switch (either high or low), i prefer the low setting but people who are heavy handed with the mouse may like the high tension setting to keep from accidental mouse clicks. Other than occupying a USB port, another reason i prefer a wireles mouse for my live performance is the extra weight that the batteries give to the mouse. The style of music i perform is very bass heavy, and often enough with a wired (lightweight) mouse, the bass on stage moves the mouse from its position which is annoying. This one doesnt seem to move at all, even when i bump the table or desk it sits on. $69 is a little steep but it was a gift so it was perfectly priced for me! i recommend it to any single-button fanatics.
