Actually, going in and out of range, one of the coolest things about the app is being able to compose posts offline. If they could add this for comments that would be even niftier. And since the best reception is often on the clifftop the phone is an improvement regardless of network, because while I could tote the MacBook out to a good reception areato use it with my old phone as a modem I’m hardly likely to bother. But I’ll slip the phone in my pocket and when it picks up a signal – woosh – off go my emails and I can stop look something up online if I need to as well.
