The E7 looks nice enough, it has the cool looking flip out keyboard and I'm sure will be a nice enterprise device.... but like the other Symbian 3 device, the N8, until Nokia/Symbian offers a good streaming internet radio solution, I'll have to pass on it.
Right now, I'm using an E72 using Nokia's S60v3 IR app, and an HTC Legend, streaming Wunder Radio.
Streaming is my killer app, because I use it on my commute, at work and between evening graduate classes. I need it for regional sports radio, indie college rock stations, and even a couple of international stations.
So, yeah, S60v5 didn't offer it, S3 won't either, so I'm going to have to pass on this gen of Nokia devices as well.
And no, TuneWicki isn't a solution for me. A work around using a limited number of Shoutcast stations isn't the same. No, using the browser doesn't work either; you actually need an Internet Radio client.
