owned several, and based sa experience ko in terms of durability - IBM! not sure if ganito din ang quality ng Lenovo
IBM - the best, kahit binabalibag ko ok na ok pa din
Averatec - after a year or two nasira LCD
Compaq - battery issues
HP - pangit specs, bagal...max nito is 2 yrs
Alienware - panalo kaso mabigat
Lenonovo - so far so good, 3 mos palang sakin
next target is macair or mac pro
