Book-tours with Android

My latest Guardian column, "The mobile revolution has arrived," describes the way that touring with a rooted NexusOne phone fundamentally changed the experience of being on a book-tour, delivering a touring author's two most precious commodities: better food and more sleep.

Travelling with your own internet source is brilliant. At Atlanta airport, I was stuck for four hours while a monster storm hammered the building with barrages of lightning. Immediately, every one of the expensive Wi-Fi networks in the building went dead as thousands of stranded travellers tried to use them all at once. I found a corner with a mains outlet, plugged in the laptop, tethered my phone, and enjoyed my own private network connection. It wasn't fast, but it was free and it worked.

I still have a US T-Mobile account from when I lived in the US, and I pay for the unlimited data plan there (which, like the Orange UK Sim I use here, has a bizarre and fraudulent definition of "unlimited" that includes a data cap). It's easily worth keeping the account alive for those times that I'm back in the US – one day's 3G savings (not having to pay for expensive hotel and airport broadband) pays for a month's mobile service.
