Good for me
I have a Netzero free account and at 9 months am tired of nursing my 200mb thru the month. After 12 months the free data expires and the data plan they offer is much more than $14/gig plus unused data expires monthly.
The Karma router is about 25% smaller and is more pocketable. It will come in handy to feed my iPhone and Nexus 7 cheaper than what the telcos want to gouge me for.
The biggest advantage is that's it's a pay as you go, no contract plan where you buy data in relatively cheap chunks that don't expire monthly as the other's do.
