He is also a playable character in Resident Evil: The Mercenaries 3D and Resident Evil Revelations.
Nowadays most laptops has a battery life of about 4 hours. Old ones bought in the 2000~2004 Last about 2 hours.
Not that we haven't tried in years past... but when you get 5-10 laptops dropping dead every month that you push past the warranty, it becomes really obvious really quickly how worth while it is to replace the things before they die. A 3 year life span is an entirely reasonable expectation for a laptop to last. Failure rates under 3 years are low, and laptops tend to stay relevant for that period of time. For gaming hardware, 3 years is a good run for staying relevant.
