Those battery life numbers that were originally quoted for the old TI 500 were under OS 9 which did a much better job of conserving power than OSX. Also it really depends on your usage and power settings. 1.5 hours may not be that bad if you are using the high performance processor setting, not turning screen brightness down substantially, or are using the processor fairly intensively. If I use the dvd player or run processor intensive programs like VPC, VectorWorks, etc I don't get much over 1.5 to 2 hrs either and I have 2 other spare batteries that perform the same. Greg
