From reading the reviews, it is apparent they don't all refer to the same product/vendor. This review is for a Lenovo Tiny M73 purchased from Micro Deal.  It did NOT include a keyboard/mouse-it wasn't supposed to.  The picture showed a wifi antenna on the computer, it doesn't have one. But the USB wifi adapter included installed and connected without any issues whatsoever. From the time I took it out of the box to when I was working was an hour; that included downloading updates and other browsers.  Machine was in very good condition and clean.I ordered it on Sunday and arrived via FedEx Tuesday morning.  VERY satisfied with Micro Deal.
