I've been traveling around for the last few months all over the place and finding the availability of Wifi interesting.
I'm still amazed that I can get Wifi for free on the train down to London, even on a standard ticket, but strangely cannot get it for free in the first class lounge at Heathrow airport, or indeed, many other airports. Those in the US seem to offer it more readily, but even there, I had no access to free Wifi at SFO, but did in Orlando.
