I asked the company a lot of questions before I bought it, made sure I was satisfied with their testing process and their guarantees... and asked how long they could guarantee the SSD would work. I wasn't too worried about the previous user because they were advertised as business laptops and more robust than the usual ones and that was part of why I wanted it. But I can't imagine there being any problem with an ex-business laptop. But that all said, if you've got the money and you like shiny things, then why not?
