"We're too small to compete" was the Palm motto towards the end, and HP buying them was seen by the faithful as a way of "getting it right" - more money and resources behind them, they'll be able to really get webOS out there.
And they did the exact same stuff they'd done two years earlier.

WHAT THE HELL? The entire webOS unit got a do-over, and still hosed it, with the budget/muscle of one of the largest companies behind it. Of course, that doesn't mean HP actually was really supporting it as much as people expected.
The TouchPad (and webOS stuff in general under HP) seems to have been treated about the same as every other model of HP laptop/desktop rollout they do. Just another SKU on the balance sheet, it'll be on the shelf for a few months, then retired and shifted to overseas support.
Amazingly infuriating to watch company after company claim to want to be a player in the mobile/tablet space, and fail continuously against Apple. It's far less that Apple's doing so much right, but everyone else keeps getting it so wrong, even with successful competitors to copy (this isn't revolutionary groundbreaking stuff any more, launching a tablet).
