What sort of battery life are you getting? I get between 2.5 to 3 hours. For a machine that rivals some of the fastest Pentium 4's out there, that's pretty darn good for me. The Athlon 64 throttles back to 800 Mhz (fixed, though there is supposed to be driver updates that allow the processor to adjust automatically) when on battery. How that translates to AMD's numbering system I couldn't say. According to AMD the 3000+ will do the work of a 3.0 GHz machine even though the processor runs at 1.8 GHz. I would assume that the same holds true while on battery power. Maybe something like 1 or 1.2 Ghz though the processor is running at 800Mhz. Either way, to get better battery performance you'd have to go to a Pentium M. A nice processor to be sure but if memory serves one that throttles back to as low as 600 MHz or so while on battery. That is one of the concessions of using battery power. If you're unhappy with your 6807, that's cool, I wish you well in finding a system that better suits your needs. But, honestly I believe that the Emachines is one of the best purchases I've made and a phenominal bang for the buck. Good luck. I wish you well.
