[quote=qwakrz;2156558]12h battery life is possible… You need an eeePC and a car battery, that should do it.
As for reality you can expect 2-3h from a normal laptop being used for very light work (internet etc). Some can do 4-5h but these will be limited in some way such as very slow graphic card etc. Then you get into ultra mini PC’s that can do 5+h, these are things like the eeePC etc
Apple have managed to get better life from their laptops by using a better O/S that can match the laptop hardware and control it better (windows has to be generic so is not as good at power management). Some Apple laptops can get 5+h of use on a good laptop, if you load windows onto the same laptop this falls to the normal 2-3h range.[/quote]
