I had to upgrade to Win 10 in order to do my taxes and I thought about purchasing the operating system and spending a day converting my existing system.  For about $10 more, i got this fully functional device and spent very little time by comparison reinstalling SW and transferring my files over to it.  The specs on it are actually better than the box I built 5 years ago, so that and the small footprint made this a no-brainer.
