[quote name='squishface']is it really worth it for that price since it appears that nobody develops for it now?[/QUOTE]
It really depends on what you want it for, I guess. The packed in "game" has a decent-enough art program with a lot of different brushes and background textures, some coloring books and color by numbers type stuff. Also a few minigames, including a semi-fun tilt maze game that takes advantage of the gyroscopic controls of the pad. Maybe the most interesting feature is the short drawing lessons that actually do provide real lessons on shadowing and perspective or what not. So, as a tool to mess around with artistically and maybe even pick up a few lessons, it's decent for $10.
If you're looking for a game, you're basically stuck with a multiplayer pictionary game and the single player marvel game (which is fun enough for a clearance game and utilizes the touch controls nicely but probably isn't worth buying a whole peripheral for).
