Hardware platform between Arduino and Raspberry Pi?

So I do a ton of quick and dirty breadboarding for various electromechanical devices (valves, steppers, brushless motors, etc) and frequently use Arduinos (Uno and Mega). I typically need a few interrupts, some PWM pins, and a handful of IOs. It is not my favorite platform (although moving to the Visual Studio plugin has been a much better experience), but they seem to be cheap, readily available, and fast enough.

However, the projects seem to be constantly increasing in requirements and I am wondering if there is another similar platform that I should look at? We seem to be moving towards more user interaction, and probably the need for data logging (maybe into a networked DB). Raspberry Pi seems like a decent platform on paper, but they are hard to come by, and I am not convinced I want to deal with a full blown OS (although any GUI will require this). Is there some middle of the road platform that is available? Or should I just look to add ethernet to a micro platform?

Thanks for any thoughts/experiences.
 
You could look at the Arduino Due. It's considerably more powerful than the Uno or Mega. The downside, though, is that all its outputs run a 3V instead of 5V. That means that the vast majority of shields and what not that were built for the Uno and Mega won't work without their own power supply.

If that's not a problem, then it could be the answer.
