I'm starting to regret that I didn't get my new iBook fitted with a wireless network card right from the get-go. MetroStar* is a new Danish venture that wants to bring wifi to use in cafés and other public spots. Right now they have seven cafés serving their wifi network, and will be adding additional spots over the coming weeks.
Nyhavn 17 is listed as one of the spots, so I bet their reach will stretch onto my favorite sandwhich eating spot at the big anchor. Exciting. Must try soon.
