I've used iBurst for five days now and will be returning the equipment tomorrow.
My experience with iBurst:
- the system is very unreliable (disconnects often)
- incredibly slow (slower than a 56k modem)
- often web pages do not load entirely
This is definitely not an option worth considering. It is nowhere near broadband speeds. My ISDN modem gives far greater performance. I live in the heart of the countries CBD (Sandton), so I don't buy the argument that its due to signal strength.
