The ipad an iPhone have largely replaced consoles for me as a primary gaming platform. The one knock on them is the lack of physical controls. But that has changed.
I saw this really neat gadget at MacWorld called Fling that gives ipad gamers a physical analog thumb stick. Or two, if you prefer. It is a little plastic doohickey that sticks to the ipad with suction cups and has a capacitive touch device mounted inside a flexible center. It looks flimsy as hell, and may well break easily, but I got one and mounted it on my ipad this week.
I love it.
It makes games like Star Battalion, Galaxy on Fire and Speedball soooo much easier to control. The gizmo obscures some of the screen, but it is totally worth it to get that precision game control.
I will be trying it on Rage HD next.
