Before the Palm Pre became official, it was given the codename 'Castle', which also might have something to do with an alleged new smartphone that Palm is currently in the works with. It's being reported that Palm is indeed planning a new device which may or may not be the Palm P102 which first appeared in a certification database.
This device which is given the codename 'Mansion' looks to be somewhat promising since it's positioned to pack on an 800 x 480 display, however, it'll lose that all too familiar Palm keyboard that long time owners have been accustomed to using for some time now. You heard that right, this Palm 'Mansion' is losing the conspicuous portrait style keyboard and will place all of its text input via on-screen options.
Although it's assumed that a virtual keyboard code is somewhere buried deep in webOS 2.0, it would primarily be meant for the PalmPad, but it'll be interesting nonetheless to see how Palm's virtual keyboard will stack up against the competition. Aside from those two notable things, there is nothing else known specifically about this handset.
