We purchased these units to put into place 3 workstations in a project management area which had some ANCIENT hardware (think 2003 people). I installed the units without issue (warning it REQUIRES 2 USB cables, not just ethernet cables, so I had to go buy those). The software installed on one of workstations without issue (Win7), though I would recommend downloading the newer vShere (v7) as it seems to be more stable. Connecting them up was simple, minimal changes on the workstation needed except to create user accounts. So far the employees have no issues except to complain it won't stream from YouTube cleanly. I have seen it myself, it starts perfect, but about 10 to 15 seconds in it lags and then the video on the screen flickers badly. I have checked all the settings and it's set to the recommended configuration... and it's not the workstation (Intel i7-quad 3.2GHz with everything in the office on Gig and Cat6). Everything else runs smooth as silk (Office, accounting apps, browser (sans video), even Pandora). For the money they're brilliant and a great cost effective way to expand a network without spending a ton on workstations. I'm knocking a star just because of the few minor hiccups during the install and the fact they show it on the site streaming multiple videos but in real world we can't seem to pull it off.
