Just got my 1070 set up, and love it. I did have a period at the beginning where nothing would work. I tried doing the firmware update, and it didn't work (I forgot that my serial port is disabled in my BIOS until afterwards), but after I put the receiver into reset mode, and then turned the master power off and then back on, it worked properly.

Definitely sounds better than the old Sony receiver it replaced, and I think its wattage (7x65) is more powerful than the Sony's (5x110), so that takes my one worry away. The remote is functional in the time while I'm waiting for the codes to be posted on the Harmony website.
