Summary: Update, buyer beware. Have used the machine for about two weeks and have to say that it appears to have problems with communications. In addition to the defective Bluetooth module, the WiFi card is not very good. In order to get a strong signal the machine has to be almost on top of the router. I have the machine located about 20 feet away from the router and the signal averages 2-3 bars. When I carry the machine to the router, it goes up to five bars.
