iPhones are quickly becoming a major player in the games market and Trinity (a japanese accessory company) has released a "gaming grip" to assist with the steering wheel type movements that are often needed in games.

This is cool in a very narrow way, but I think most people are playing iPhone games in quick bites while waiting in line somewhere and it might be a bit conspicuous playing with a bright blue steering wheel (however ergonomic it may be) while waiting for the bus.
