i guess it depends how you look at it ... for $100m they are certainly going to get huge mileage for their Brands - its like marketing drive for HP, WebOS, WebOS App catalog etc. + they will make some money by selling apps. Also one has to remember that this brand value creation will help them fetch more $$$ when they decide to sell their h/w business and WebOS business (either the whole OS or licensing it) - All in all $100m is worth loosing (spending) :-)
In fact they should turn this accidental success into super-success by creating HUGE WebOS ecosystem for at least a year and then decide what to do with it - they can get more money by selling or licensing the whole ecosystem with millions and millions of users worldwide than wrapping things up pre-maturely ... also can you imagine how much they could make if they start streaming & selling music, movies, ebooks etc. thru their ecosystem ...
