We had a WiFi enabled plane when we flew home from Seattle at Christmas. We happily paid the $5 for the novelty. But a word of warning, it was incredibly slow. We had been watching an episode of a tv show in the terminal, and we had 10 min left, so when we saw the wifi, we thought we would be able to finish it. It took 10 min to load the ABC player, and it buffered horribly. So we gave up on it, and just tried to surf. It would go in spurts where sometimes it would load a page quickly, but other times it would take minutes to load a page. On a short flight, you may not think the $5 was worth it.
