Just as bigger isn't always better, smaller isn't always great either.
I don't want a cell phone the size of my index finger. I don't want a netbook with a tiny keyboard and in the same vein I don't want an MP3 player with one button and no screen. If this works for you, cool but count me out of this one.
The previous gen shuffle was great for the gym. It weighs almost nothing and the controls are easy to use. This one adds weight to the cord and forces you to use iPod headphones. Both of these changes are inconvenient for those who use these at the gym.
It's like the mini displayport on the Apple/ATI 4870... just rubbish to force people to buy unnecessary adapters/cables. I have a Mac Pro, but I'm not getting that 4870 - not for $350, what a rip off! I'll get a regular 4870 X2 or a GTX 285 and bootcamp Vista 64/Windows 7 instead. My second gen Shuffle is working just fine and I don't foresee upgrading anytime soon, least of all to this new morse code version.
