The Adagio line gets a bad rap, I think, since they DID have some ridiculous components at that time. Like those in-wall IPOD looking things. But the AES and AMS units were pretty solid units. Considering they came out in 2006 and you CAN still service them with current software, it's not too bad. I do know of one that's still operating a customer's house.

And I think Home is actually "Pyng OS3". When you consider the legacy support they've been building into Home (for ex. the BIPAD8 audio switch from 2009), I think it shows that they're at least making an effort.

I think Prodigy is a better example. That stuff was its own line, incompatible with the legacy Crestron stuff (until way later when you could do some kinda janky hacks with firmware). That whole thing kinda sucked.
