I really don't get Pathfinder, myself.
"Hey, they're abandoning the 3.5 audience! Let's make a game that's increasingly incompatible with it ourselves and tout it as an alternative to the other game that's not as compatible with it as we'd like!"
Hooray? New abilities, bucketloads of feats and other changes now mean that Pathfinder itself is the kind of game that Pathfinder was a reaction against.
That's not to say many of the changes aren't a good idea -- nor that I won't immediately snatch up Paizo's gnome sourcebook, when and if there is one -- but "hey, don't go to 4E, go do this other game that's also not 3.5 instead" seems sort of surreal. If I were open to that, I'd be looking at Unisystem and GURPS and Burning Wheel and Savage Worlds and a bunch of other stuff, too.
