I can hardly believe it but I’ve now owned my latest laptop — a Dell Inspiron — for nearly three years. When first purchased, it was all sparkly and new and fast and well, just about everything I wanted. It’s still pretty darn fast and the hard drive has gobs of space on it, but it’s starting to show its age with periodic crashes and freezes. And most annoying, the wifi routinely requires tinkering. And the stupid thing weighs a ton (well, not really, but it feels that way when stuffed in a bag or pack along with everything else I need to carry).
