Absolutely. With "only" 3+ hours of battery life with a 50Whr battery, those Core Duo systems won't even survive a drive to Seattle!
But... at least a user can unplug their faulty USB device and get the battery life that can. Too bad AMD systems don't even have that option, according to these tests.
LOL, yourself, it's no worse than my Dothan notebook. An AMD notebook with a USB notebook mouse wouldn't last an hour. I use mine on batteries with a notebook mouse all the time.
