Since we have some folks here who enjoy both real-life MLB and the Nintendo DS, I'm wondering if people know about this and what they think of it (as a non-DS owner myself, I wish it extended to any WiFI client device, but I can understand their interest in keeping it DS-only). I'll probably try one of the rental DSi units just for the heck of it. Right now it's just being tested at Safeco Field (home of the Nintendo-majority-owned Mariners) but they'll probably roll it out to other parks eventually. The Seattle Times had a longer article about it.
