@dave999, I did that in the first post, my problem was if I should wait for the next Nseries or should I choose the phone presented.

@superkinggt: you see my point, I need to take my calls, every single one of them since they might be work related. I can't call them back later since they are redirected from my office phone, and I'm not in the mood to call someone half way around the world on my expenses.
I'm usually cruising at 45-50km/h and currently I can use my e51 on the bike with no major problems, but the e51 doesn't do voip, web browsing, emailing as I would like.
