i beg to differ. but only dell which is good is dell adamo.....
dell is know for bad batteries and sudden mainboard failures.....
i have used extensively hp, dell, acer, sony and offcourse IBM.
My 5 year old T43 still works for 2 hours on battery without any hitch
my dell inspiron has eaten two batteries in 4 years
hp is however better tgan dell
currently using T420 core i5 with 15 inch screen. extended battery works for 8 i repeat eight hours
sony is good in terms of battery aswell
