I'm a baseball nut, I admit it. Until recently I had only bought 3 or 4 iPhone apps and the most expensive one was $1.99. I had been using MLB's At Bat 2009 Lite edition before opening day and I didn't even flinch at the thought of paying $9.99 for the full-fledged version. I'm glad I pried open my wallet for this one.
The pitch-by-pitch, in-game interface is nice and all, but the killer app for At Bat 2009 is the audio feed service. No matter what game I want to follow I always have the choice of not one but two radio feeds from it (home team or away team). So when I'm catching up on the Yankees game I can always be sure to hear the wonderful John Sterling as well as the annoying Suzyn Waldman. (See? She even spells her first name annoyingly! She's begging to be parodied on SNL, if she hasn't been already.)
I've been on the road a bit since the season began and I'm happy to report that the audio feeds have been terrific. I've tried them via 3G and wifi and couldn't tell the difference between them.
The video features are nice for highlights but I have to admit they're awfully grainy on 3G but spectacular if you're on wifi. But if you're committed to running wifi while using this app I hope you're close to a power source. The audio streams for At Bat 2009 will suck your battery dry faster than you can say "Batter Up!".
Overall though, if you're a fan of the game this app is a must-have.
