So far, lovin the N1. ShopSavvy is a great app; ive spent way too much time scanning random products in the house to see what kind of deal I got. Also confirmed that TJ's really does have good deals on mid-grade wine, after 25 minutes scanning there (with annoyed kid in tow).
I crave an app that allows the GPS/direction thing to broadcast through my car bluetooth, as the speaker on the N1 is a bit too quiet.
