What is the normal lifespan of a laptop? The manufactures would like for it to be 2-3 years.
I have a few Ibooks with OSX that I still use that apple stopped supporting a while back. I have a 12 year old HP that I use everyday. Sure they are slow by today's standards but they still work and do what I need them to do. The HP has been a workhorse being on for around 8-10 hours a day since around 2001.
