Hello... Is it a usual for Apple's Magic Trackpad to go through batteries like nobody's business? I've been using Apple's rechargeable batteries/charger, and whilst the Wireless Keyboard is still on the same charge since May, I reckon I've been changing batteries in the Trackpad near enough every week or so! I understand the Keyboard requires a lot less juice to run, but really?!?! I used to use the Magic Mouse before I got the Trackpad, and I remember changing around every month or so... Surely the Trackpad can't be hungry every week?! Or is it Apple's rechargeable batteries that are the weak link? I was using Duracell batteries when I had the Mouse... I will continue to feed this beast because I love it so, but I fear I may end up getting eaten if I ever run out of charged batteries!
