I now intend to buy my laptop not from a shop but from someone else. But before, I'd just like to know: what can I expect from a 1-2 or 3 year old laptop in terms of durability, to which extent will it be affected? I tend to keep my computers a long time, so it counts (I kept my last computer 5 years).
Someone knows the average lifespan of laptops? Or even better: anyone would know how to have an idea of the average lifespan of each brand (IBM, Toshiba...)?
