I was expecting that that the game was aimed to iOS devices because of those pictures, kept reading waiting for the revolutionary touch interface to be mentioned
I never thought about SimCity (or any city planning game, really) on the iPad. In hindsight, it seems like a great idea. Most of the game is placing long strips of transportation and utilities, like power lines and roads, or zoning large areas. Both of these tasks are well-suited for a touchscreen display.
Unfortunately, it sounds like it will be PC-only (or PC/Mac, depending on which article you believe).
I haven't had much problems with it, and have played it for quite awhile. It's crashed a couple of times, but never lost more than a couple of mins of gameplay. Definitely worth a couple of bucks.
