Ah, somebody hit on the freezing issue!
Unfortunately, I have an issue that for sure precludes me from jumping on new Pods. One of the "dirty little secrets" of the Pod. I had an increasingly seriously (and annoying/disruptive) problem and the other day went to the support discussion boards at apple. Spent about an hour reading posts of people afflicted with the same issue I had; and ALL of those posts were within the last 4 days!
The consensus seems to be that if one is moving while your Pod is spinning the disk and reading songs into the cache, it will freeze. As in need a hardware reset, as in wiping out all the playcount data collected so far.
Which is probably why I see so many folks holding their Pods in their hands. Which is why the "for the active lifestyle" is BS.. the Pod is PERFECT for the sedentary lifestyle, and problematic for being too active. And lemme tell you, a lot of those folks are runner, most of who were reassured by Apple Store employees that the Pod was the PERFECT companion for the runner.
Naturally, apple is saying exactly nothing.
And it's really quite simple to address this issue (which undoubtedly came about by them shrinking the size of the units; clearly reducing shock absorption material for the HD). The solution?
1. up the cache size; 128M would be nice, but I'd settle for 64M
2. introduce a software setting that says "play cache and stop," so that before it CAN freeze, it would stop playing. Put it in your hand (while exercising), choose another smart playlist, count to 10 and you can then go on about being, er, active.
I will NOT buy another Pod, nor will I encourage ANYONE to buy one untill at least 2 is implemented (and not just for new Pods, if they don't cover at least 2G units, fugeddibouditt) and better both 1 and 2. Unless the person knows they will never try to walk, run, jog or do anything active while trying to listen to music.
