I’m an entusiastic user of the E61. What I like the most is that I can place free VoIP calls with the same user experience of a GSM call (I’ve described here how the E61 and N80 can be setup for VoIP).
But what I really miss was a camera! Now with the presentation of the E61i at 3GSM (covered here by Luca) I’ll look forward for this new model.
