A copule of screens from the forthcoming webOS tablet, the HP-Palm TouchPad, which show Bing as the default maps provider on the device are leaked. The screens are reportedly authentic because they were obtained from the webOS 3.0 emulator.
What this also suggests is that on HP-Palm devices beyond its TouchPad Bing could be the default mapping provider. (HP has a toolbar/default search deal with Microsoft.)
The problem for Bing is that unless HP prices the TouchPad competitively and aggressively it's unlikely to sell very well. Even then it might not. The same is true for new webOS handsets, assuming the shift is being made across the board.
Here're the screenshots:
