Could you share with us WHY do you think that is the killer app ?
Because I can cut my telecommunications bill practically down to zero. Most of my phone calls are made at work and home, both of which already have WiFi, but then there's also The Cloud in London, which is city-wide hotspots for about £10/mth.
From what I see, VoIP via WiFi in phones/PDAs is the re-creation of GSM technology but without the phone-orientedness of GSM networks.
No, with VoIP via WiFi, GSM simply becomes the more expensive supplement to WiFi, to ensure mobility.
you seem to have worse autonomy
No, because you'll still have GSM, and WiFi actually ensures the carriers lose control over you.
worse coverage
No, you'll have better coverage, as you'll have the potential to use WiFi when there's no GSM coverage.
extra HW cost, bluetooth interference, limited and country-specific list of channels,
???
but hey you have the extra bandwidth you will never need for VoIP !
No, you have already-paid-for bandwidth for VoIP and video.
Pricewise, it's bust again.
Calling my friends in London and my parents across the world for free from a mobile phone really is cheaper than my current arrangement, I can assure you.
No carrier will subsidise such phones
Another positive. Finally their grip will be loosened. The economics are rather obvious if you ask me. It would take well under a year for me to start saving money if I went out today and purchased an unlocked Nokia N80, put Truphone on it: http://truphone.com and got some prepay GSM.
