I have mentioned both of these products here before, but not together. Last summer, I purchased the Karma Go portable 4G wifi hotspot to take camping. The hotspot is pay-as-you-go, so there's no plan and no contract. Simply load it with data (about $14 per gig) and use as little or as much as you need. The data never expires.
The Karma Go requires web site authentication to use it, so you must have a web browser, you can't just enter a wifi password. Recently, Roku launched an update for their streaming stick to allow it to talk to wifi hotspots that require this sort of access (click here to read that post).
Last weekend, I moved to a new house and I don't have cable yet. This was a problem for Game 6. My family wanted to watch the Cavs, but we didn't want to go to a bar to do it.
We were able to live stream ESPN through the Karma Go, to the Roku stick and onto our TV...in full, high definition.
The Karma Go costs $119 at YourKarma.com (data not included...get 10Gigs for $100).
*streaming the game at up roughly 1GB of data.
Roku Stick costs $50 in stores or at Roku.com
