At the time of the Pre launch, the speculation was that Palm could afford to piss off Apple as their patent chest included some real gems from their work on the Palm Pilot and on Treo smartphones; I have a vague recollection that they had some key patents required to build a smartphone address book that Apple was already likely infringing.
On a similar note, I find the idea that future non-Apple devices might have been required to be triangular absolutely hilarious.
