I go on this one... Toshiba repairs, few and far between.... HP repairs, very common, esp cracked cases - however that may be down to HP being cheaper and therefore more popular... I own a Toshiba and 2 HP's... Not in the same price range - Toshiba has better build quality, but less features.....
Please do not go for HP. I have seen many issues with the HP video and LCD. Having said that, the high-end HP laptops seems to be OK, but pricey. Anyway, you will not find a reliable HP laptop under $800.
Toshiba on the other hand, is way higher than HP when it comes to durability and performance. (any Qosmio series)
My last four laptops have been Toshibas. Two of the four have had serious overheading issues.
Satellite L305D Serious Overheating
Satellite P205 No overheating
Satellite A45-S150 Serious overheating. Bought P205 because processor would continually shut the system down on high heat.
Toshiba 2805-S503 Minor overheating problems
