lol, wifi from the beach. The big thing about wifi is that it sux ass and always goes down in open areas like that, shoddy coverage. The new cell tower stuff would be better than wifi if you are out on a board, although that would be pretty cool but really, I have that on my pocket pc/cellphone I bought from Dubai, just waterproof it and you have a pc.
The interesting thing now is getting internet through your electric company just by plugging into the wall. They want to get in on the act too. Lots of stuff coming soon
