I'm reading this forum on a 2010 Sony Vaio. I recently thew away a 2009 Compac laptop. Our 2011 MacBook Air has just gone beyond repair with a display sceen and battery problem that wouldn't be worth reparing. My main PC serves me fine, of 2010 vintage. I have some newer equipment too, but old laptops can serve you well depending on what you need them for. On average, a computer will serve me for over 10 years. The old machines do get some upgrades along the way and I also pull them apart and give them a good clean, and some fresh thermal paste.
