I don't actually mind either way, but I agree that cross-class skills in standard d20 are a bit on the expensive side. Well, pretty much not worth the bother, most of the time.
Pathfinder's way of handling it looks good, but I haven't tried that just yet. Give it a week or so, and I'll have a better idea of how much I like/dislike it.
Anyway though, for class-based systems, some kind of class skill setup makes sense, to me.
