Ten Tec 506 Rebel

It's a 20/40m QRP CW radio. The neat thing though is that the CPU in it is Arduino powered. The whole thing has standard connectors and all kinds of standard, easy to work with, parts. The complete opposite of ridiculously expensive closed systems like the Icom D-Star radios. I think it would have been more fun if it wasn't just CW only. Even something geared more toward digital modes than voice would have been nice. Still, this is a very good direction to go in after tons of radios that are completely closed off (and really fly against Ham radio tradition) or radios that are otherwise built completely without digital components at all.

Not that there's anything against roughing it with the same functionality as radios had 50 years ago for nostalgia... but there will be no innovation if you just do the same thing you've always done. Without innovation, Ham radio is doomed.

Now I'm waiting for a series of radios that include an empty bay for taking things like a Raspberry Pi or Arduinos or whatever you can squeeze in it.
