i picked up the 670 yesterday for my wife in the bedroom, and just had to post as to what a dream it was to program!! Coming from a Nevo SL, and most recently the MX 980 programming software, i have to say Harmony is hands down the best from a DIY perspective. it does almost everything the higher end software does but MUCH easier! while it may not provide some of the intricate detailed programming of the SW's mentioned above, as an end user i never have to bother with them anyways.

i can see this software would allow me to EASILY accomplish a setup for my own media room, and i REALLY look forward to the day they release a model that is to my personal taste. also some additions to the programming ie: being able to use custom backgrounds, "press and hold" commands, toggle commands, picture of the remote while you are programming, etc.

the 670 itself is a good feeling unit, unlike the 880 my friend has that feels a little "creaky", the 670 is quite solid, and the definition of the gem buttons is very nice.
