Blu-ray on the road ? I wonder if it's of any use at all and can play a couple of films without being plugged in. It's a fine piece of kit with powerful hardware, can it last “on the road” I doubt it.
It reminds me of the first few years of sony's portable dvd players, they couldn't play a full movie without running out of battery either.
Edit just checked.. 1.5 hrs life. That is no doubt with screen turned down, drive not spinning etc, taking real life usage to less than 1hr.. Useless.
