This was an amazing value, but my goodness is the battery life abysmal. On a full charge I get about 2-3 hours of operation. Not sure why that might be. The cell might be bad, but this is how my particular unit arrived. The power brick is quite large (approx. 1 in. x 3 in. x 6 in.) and heavy (almost as heavy as the laptop itself), so carrying it around with me all the time, and needing to plug in often, defeats the purpose of the laptop's inherent portability. Otherwise, it's a great piece of hardware.
