The only thing I know is that just today my 8 year old son and I were watching cable TV and saw an ad for Vonage ($24.95/month). My son asked me who would get Vonage because you can get MagicJack for $19.95/year.
I guess, personally, I'll stick with Skype.
I guess MagicJack looks very lucrative in terms of pricing. The real testimony is how they continue supporting quality service
Explains how they get those commercials run alllll day on the television.
Talk about first mover's advantage. Also this guys do a lot of infomercial.
