Dude, I looked online and the battery that's in my computer now (6 Cell) is $100. So yeah, You could buy a long lasting battery but you couldn't afford a laptop to go with it. Also, I don't see what is so bad with my Satellite C655D. Sure, the GHz are crappy, but the only thing I noticed was taking a while for the engine to initialize when I start BL. I bought it for $250 and the screen size is 15.6".
