I agree, it IS just a device, and not something much more important, or of irreplaceable value... Keith is absolutely correct to point this out.
The issue here, is, sadly, that this was such a sudden turn of events. Even the HP employees are probably shocked over this... anyone who says that there was "writing on the wall" is deluding themselves.. I believe that HP made as sincere an effort as their corporate drone hearts could.. (but, they needed to be just the opposite of that, in hindsight), and the new CEO never really gave it a chance.
The incredibly stupid thing that was done was to announce this, and the poor sales, and the decision without any future plans set. They have options, but no concrete plans going forward - by making this decision public, they reduced WebOS's value significantly, and destroyed any sort of bargaining they could do to keep it a viable OS with revenue potential, other than the patent portfolio.
So, unless they announce a licensing deal that is already in the works an djust couldnt be announced (I highly doubt that), they will have to spin it off with the PSG as a standalone (Palm back to being palm again with no money), or sell it off to, say, RIMM, who's been emulating the WebOS OS with QNX, and would probably love to have the patents to own the right to do it without punity.
I can't see, after yesterday's poorly executed annoucement during these half baked hardware launches, a hardware company buying or licensing WebOS. There are too many proven alternatives out there already.. no need to risk going into one that has just, well, acording to HP themselves, FAILED.
Its just mind-numbingly stupid, this whole sudden change of events.. and it stinks from the very top of HP; they have how many devices out there now, that they need to sell?
So, in answer to the OP:
This is nothing to panic about, but, if you like your Pre/Pixi/Pre2/Veer/TouchPad, its something to consider in using your device going forward, and for future purchasing decisions... change is something that we all must deal with in life..
Perhaps there will be a new group of WebOS diehards who refuse to give up their devices and just keep modifying them, despite having no MFR and carrier support for them.
As for me... Im still thinking this through, and over the next 2 weeks for so, I will certainly have to make some rationalizations that will work best for me.
Not panicking.. just very alert and certainly paying close attention now.
