Hey, I used my new PowerBook (15"/1.67GHz/2GB RAM) out in the wild for the first time today, I was using it to take notes during a lecture. The problem I have is that the battery went dead before the two hour lecture was over. Admittedly I had ripped a couple of CD's beforehand and was running Freehand, Calculator, MSN, Firefox, Airport and Bluetooth (Mouse) at the same time, but surely I should've been able to get more than two hours out of it! The guys next to me on their iBooks were getting about six or seven! (I know, slower HDD, less RAM, less intensive VRAM, slower processor, etc, etc.) Anyway, now I'm thinkin' I should invest in another battery. For now I can find a power outlet, but I'm going to be recording in remote locations with Pro Tools throughout the year and I need to know that my PB's not gunna die on me. So... does anyone have any experience in the battery market? Is it at all like the RAM market (heaps of brands, varying prices), or is it pretty limited?... Also, I was checking out MacSales.com and they had batteries which promised 11% more battery life... is it worth paying more for these 'extra capacity' batteries, or are they dodgy? Any help would be great! Tim.
