Maybe the Zune HD WAS the testbed for WP7?!?
Still, I can't seem to understand why they couldn't open it up for programmers to legitimately create and sell apps for it. I know the screen resolution is not WVGA but is it really that much work to give the programmer the option to offer his/her program to the Zune HD owners as well as WP7. I mean, if they choose to invest the time to tweek it to run on it, good for them...
(Now that Twitter & Facebook are finally out, I'm waiting for an e-book reader to capture all of my entertainment on the HD)
My real concern has always been Microsoft's view as to what is "disposable". If they thought the Zune HD was to bridge the gap to the WP7 devices or Zune HD V2, that's fine if they had priced the Zune HD agressively or come out with a reasonable buy back program to purchase the new version. Doing either or both would have been acceptable for me to consider moving up to a new player if the new investment was kept under $100 to $150.
Otherwise, like all of my tech from before, I'll be holding onto my HD for the next 3-4 years (or until my wife let's me buy a new one!) and I will sit and stew as everyone else has cooler toys to play with
