In the interview with "This Is My Next" (http://thisismynext.com/2011/07/14/dewi ... exclusive/

TIMN: Okay, let’s move on. You have a new smartphone coming, I know you have printers and other stuff, but you’ve got the Pre 3 coming. It’s running a different version of webOS than the tablet. There are pretty major differences between those OSs. You’re encouraging people to develop for webOS 3. Is this going to hurt the Pre 3? A device running an older version of the OS? Do you expect to get them to parity quickly? What is the phone outlook?
Jon: I wouldn’t say it’s an older OS. It’s certainly a different OS. We didn’t want to do a tablet where we just took the phone OS and scaled it up. We talked about this before. We went back to the drawing board and said ‘how do we take webOS and deliver that elegant experience but optimize for the larger form factor,’ and because of that we had to split the effort. You can assume that sometime in the future will converge again, but not anytime soon. So you’re right, the Pre 3 has a different version of the OS. It runs phone optimized applications, it’s not going to run the tablet apps. That’s how it works on every other phone that’s out there.
TIMN: But you’re still encouraging developers to code apps for the Pre 3′s OS?
Jon: Absolutely, and we’ll do something in the future that will make that easier for developers, but we’re not going to talk about that now.
TIMN: Will they hit parity soon though? Before the end of the year?
Jon: We’re not giving any timeline on that.
TIMN: But it will happen?
Jon: No, I haven’t even said it’s going to happen. I chose my words very carefully. Sometime in the future we will re-converge these, but right now that’s not the plan.
That is, the outgoing head of HP/Palm explicitly declined to commit to end the fragmentation between webOS 2 and webOS 3 in 2011.
HP/Palm previously announced that devices released after 2011 would not include Mojo.
Thus, apps targeting the Pre 3 would appear to have a lifetime of about four months. That's not much time for return on investment.
That is, unless you go to a third-party framework not supported by HP/WGBU.
So, HP's message to consumers is "webOS will unify your data", but HP's message to developers is "You need to write two different versions of your apps this year". So, there's a strong incentive for developers to go elsewhere, and maybe take a look again next year.
