Summary: I have bought refurbished desktops and laptops before from other companies for myself and employees. I am pretty technologically savvy. I had been using an XP based system, which was a refurb I had owned for 10 years. But, the time had come to upgrade to Windows 7 or 8 with XP support fading. I wanted a faster system, so rather than rebuild the current box, I just tried this out from Overstock. I took it right out of the box and pugged it in....so far so good.
