I've been following your adventures, I'm going to New York myself in a couple of weeks. Any resteraunt recomendations?
How do you get wifi on the plane?
New York is great. If your not taking your bike their are loads of bike hire places, the main one is Bike and Roll, you'd be hard pressed not to bump into one on your travels. I can recomend Rosie O'Gradys for great steak and Irish American food, Edit: Rocky's, on W57 street, American Diner style bugers and what not, and Carmines, a bit of a tourist trap, but great fun Italian style food, but be aware, just order one item 'cos you won't be able to finish it.
As for wifi, some of the newer American Airline planes are testing out, and at the moment it's free, our outbound flight had it, but the inbound did not. If you take an IPad with you you may have trouble checking the agree to T& C box because of the formatting, so just clear your cache and then try again and you should see the check box ok. I'm not sure if other airlines are doing Internet.
If you can take a short trip up to Peirmont about 20 miles away, a lovley small town America place with great places for a coffee and lunch, it's beautiful ride or drive. There's a fantastic cycle shop on the way too, to have sniff at, called Strictly Bicycles.
