Best and Worst WiFi Hotels 2007

The best and the worst Wifi Hotels 2007. You'd think with the prices that you pay to stay at some of these hotels, they'd throw in WiFi for free i.e. include their infrastructure costs into the room rates. Take my stay at the InterContinental The Barclay in NYC for example, free WiFi in the lobby, but pay if you want it in your room. Why stinge just because the Marriott across the road is doing likewise? Is there a study somewhere that shows a greater uptake of rooms with free WiFi for business travellers?
