Not to seem argumentative, but I have a cellphone and an N800 and I feel naked without the N800. The cellphone doesn't get much use since I bought the N800 last year. In fact, I switched to TMobile's pay as you go in the USA and haven't used $50 worth of it in ten months. I can leave the cellphone behind when I travel, BUT NOT my N800.

I am interested in this thread because it claims there is a Skype killer out there. After reading though the posts I have to agree that another 2 cent per minute SIP service provider is just that.... not a Skype killer.

Skype's $2.95 per month unlimited deal is good for those in the US and Canada who talk on the phone a lot. It can work out to way below a penny a minute for them.

Several SIP providers now offer 1 cent calling to PSTN in the USA. Look into Future-Nine.com and Webacall. Many SIP providers simply email your voicemail to you as .wav files, but Future-nine has a very robust voicemail system in place. I am not affiliated with any of these operations. I am just a user.
