So, okay... which "other programs", specifically?

Poser's only direct competition right now is pretty much DAZ Studio and iClone... at least for software that costs less than $500 or so, and doesn't require a zillion plugins.**

There's a couple of other suites that come in between $500 and $1000, and after that, you'd better check your credit limits.

Not saying Poser should stand pat, but seriously? Trying to reach about and cover every conceivable base will destroy the application's efficiency, usefulness, and UI. If Poser can do all that DAZ Studio can do and maybe a bit more, then it's ahead of the game.

** I'm sure there are probably others, but they're likely too obscure, too specific/platform-dependent, or don't carry the same feature set.
