I got an email back quickly, shown below
We're looking at WebOS. Currently it does not have a big user base,
and as we're an ongoing service, every platform we support is a long
term investment - its not just a case of port once and forget about
it. Every platform must be maintained, fixed and updated. However
WebOS does tick the technical requirements better than, say, Windows
Mobile 7 or Blackberry. So we're watching to see if WebOS can gain a
big enough market for Apps to justify the costs. However HP have just
apparently contacted us, so who knows?
so they seem interested, but just worried about the small number of users, perhaps if enough emailed them, they would make it sooner rather than later.
But with HP contacting them, i hope they bring it really soon, and i hope HP are contacting many other developers about bringing more high quality apps to webOS
