I've heard from many that the newer (not sure what to call the generations of actual dishes) are much better, and that it has fixed problems with connectivity, speed, reliability, etc. I've got the very oldest, original - how do I get the newest version? I'm tired of expensive, poor service, and wonder if this might actually be at the heart of the problem.
