It seems like every two to three years I'm getting sick of the laptop that I constantly work on. The reason being probably is that it gets beat up from all the different environments that I work in. You would have to have a bullet proof case on some construction jobs. The last one I replaced was completely broken in half as the guys set the materials to close to the bench I was working on, it collapsed. I hope the new acer aspire laptops that I purchased will have a longer life than the last one.
