Another thing, it feels like the Tablet P was designed by Sony's phone developers rather than the team that designed the Tablet S. The removable battery of course, but the storage structure that requires a Second SD card to be installed. It deals with the storage exactly the same way my phone does. Sure it came with a 2gig "sample" card but it was plain you had to immediately invest in heftier storage. Also App2sd is present here as well. It is just a unique tablet design all the way around.

Tom, that's an interesting observation. It's quite possible that the P was developed by the "phone crew" instead of the normal "tablet crew." Either way, the current issue is that when the P didn't sell in big numbers, Sony throttled back the P tech support to bare bones.
Sony should still keep the P. It's unique design has a following, and (if supported) would always have a niche in the tablet market.
