Here's a neat little tidbit for you iPod users out there
who may be travelling to Europe in the near future. On mycitymate.com you can
download a guide for select destinations including Berlin, London, Rome, and more.
I downloaded and copied the Berlin guide (free with registration) to my iPod nano. The guide is well formatted and each subsection is organized by neighborhood or category. They're not exhaustive guides, but for a free (with registration) collection, the mycitymate guides are a great find. I especially liked the handy "Nearest Metro/Tube" note at the bottom of each entry. Snazzy!
