I am also turning blue, wanting the WIFI feature. But let us be fair! Implementing something like that will likely take an enormous amount of work as a menu for connection options will be needed, possible encryption options, and obviously, a browser. Everything is available on the market, but the integration will be a handful.
I have a WIFI dongle as well as a USB memory stick connected to my iFly, just hanging around, waiting for something to do! Walter will get there, but it might be a long road. Meantime, I carry a laptop with me and use it to get updates at various airports, transfer that to the memory stick, plug the memory stick into the iFly. Not sanitary, but 100% functional.
