We purchased 3 of these machines for an immediate project and ran into issues right out of the box.1. Every machine contained a different image of OS at various level of patch update.2. 2 machines required extensive firmware updates, 1 did not.3. They are advertise to have Wifi - which they do with a help of external USB adapter that tops out at 10Mbps, and stops working within an hour. One machine had a dead USB wifi dongle out of the box. In other words, we had to spend additional money to get Wifi working on these.4. One of the machines was covered with black vinyl cover, assuming to hide scratches. That vinyl began to peel off on 2nd day.
