I use the game functions on my phone every once in a while -- when passing the time waiting for a movie to start mostly, but, generically, anywhere where I'm waiting for a short period of time with nothing else to do. At the same time, I can't imagine I'd ever pay money to play a game on a cell phone, which seems to be the big push behind these new games (I blame John Romero). I'd much rather play one of those pebble games or growing worm games for free.
