Too little too late IMO. Palm has, to date, been unable to provide an update for the Treo 700P to clear up a myriad of issues. Releasing a new browser is nothing more than putting clearcoat and perfume on a turd. It'll likely have issues too as it'll probably have some form of conflict with other bits of 3rd party software.
Unimpressed. Unenthused. Uncaring.
