Out of the box, the PC was great.  About 2 months in, Bluetooth stopped working.  I contacted tech support multiple times, and they gave me nothing useful.  I let it go and got some plug-in speakers.  Last week, Ethernet stopped working.  Audio stopped working.  Microsoft Print to PDF stopped working.  When I try to update drivers, I get errors.  I have contacted tech support 3 different ways, and they have not responded.  Customer service is beyond pitiful, and the machine appears to be a lemon.  Too bad it's not still within the return window, because I most certainly would.
