I was very pleased to hear that Chicago O’Hare finally has wifi available for travellers. They’ve been lagging behind other airports in that regard. Previously the only option for getting online were booths where you pay around $5 for 15 minutes access.
The new system is not free, but it does seem to have pretty good coverage across the terminals. Unfortunately it is also painfully slow quite a bit of the time, making me wonder if the convenience of being online is worth the frustration of waiting quite so long for sites to load.
In true “web 2.0″ style, the service is marked “beta”. Hopefully that means it’ll improve with time.
