I bought the last Ti battery from the Apple Store in Chicago in the Spring of this year, and it made a WORLD of difference. I got close to four hours of pretty strenuous work. My new AlBook (tricked out with the 128MB VRAM and 5400 RPM drive) gets pretty bad battery mileage, even with Power Saving in effect. But, hey, I didn't get it tricked out for battery life. Anyway, perhaps you can find an Apple battery through a catalog reseller like MacMall or MacWarehouse. Pete
