But Open Garden does work. I have it on my Win 7 Lenovo laptop and my wife's Nexus 7, and download speeds by speedtest are 0.8 mbps. I only have 3G here in central Virginia. But this is viable. Unfortunately, there is no app for my HP Touchpad.
But Open Garden would be fine with 4G or in a pinch. No issues and it's free.
Unfortunately, that is not viable for everyone. I will repeat what I wrote previously...
"From what I can see, no other non-root app could do what FoxFi did. They all require
proprietary "software" to install on the target device, meaning it will
not work with all tablets/devices, and many offer
no Linux support."
With Open Garden, it is even worse:
* No Linux support. No ipad/iphone/itouch support.
* Pairs whether you want it to or not, as long as bluetooth is on.
* They are trying to be more than a hotspot, they are running "services" all the time, including GPS.
* These services drain the batteries in all devices.
* It also seems to be geared to want to "share" your bandwidth with other people, which might not be what you want. There are NO access controls.
* And because it doesn't look like a network connection to client programs (especially on tablets), many apps will refuse to work at all, like Google Voice Search, Play Store, and many, many others.
* One comment from their team seems to indicate it also sends back all kinds of info and/or depends on their "opengarden" servers on the Internet (connected through Amazon EC2).
