Nope it's not. VoIP is not a mobile phoning solution, it's a nomadic phoning solution. The difference is startling, even if many seem not to grasp it.
Basically, WiFi is not a setup-less protocol. Commercial (and many non-commercial too) hotspots require you to log in. Plus there is now way to be sure if the network connection is ok for VoIP (be it firewalls, bandwidth problems, jerky connections). So basically, it allows users that want to go through the pain to take their landline with them, whereever (hispeed internet capable) they are. Please also consider that using hotspots on the run is quite expensive. In my personal experience, I almost never bother. The only times are when I need something to do latency free and/or I forgot to bring my mobile-warrior pack with my laptop. To put it bluntly, consider my poor guy, sitting in the Frankfurt/M train station, wanting to call his wife in Austria. What is the cheapest way to go at it? Hmm. Calling directly from my German mobile ~60EUR per hour. Calling from my Mobile via Calling card ~4.20EUR per hour. Calling via "free" VoIP via hotspot 12EUR per hour. It's worse, because the first two options are billed per minute, while the T-Mobile hotspot bills at 10 minute increments. So a VoIP phone allows cheap calling where you've got a free hotspot. E.g. at home. But at home, I can just use my landline directly to call cheap. And everywhere I've got a landline, I can call the 0800 free call dialin of my calling card provider. So VoIP "as cheap call" feature helps only in a strictly limited number of places: free hotspots without landlines that can be used to call 0800. E.g. some hotels have free WiFi. Good. But the same hotels have a phone in every room that I can use for free to access a 0800 number. Bad. So, while it's cool, and it has many nice uses, I don't think that VoIP/WiFi on a mobile is a killer feature. Actually, I don't see that many other uses for WiFi on a phone either (I don't use it much on my Nokia I admit).
