I'm a nomad, and I admit it. Put me on the road and I'll find what my heart lusts for. Wine, food and Wi-Fi. And the more time I spend in Europe, especially Spain, the more I find Wi-Fi in coffee shops, retaurants and gastro bars. And it's basically free.
Sure, you need to ask for the WEP key, but as a solo diner at times, being able to stay connected indoors, through the thick walls that makes 3G connectivity a challenge, but the restaurants and coffee shops are quick to offer the access to customers.
Sadly, I find less of this connectivity option in USA dining establishments and feel we're lagging behind. In essence if the cable operators and telcos in the USA worked WITH the dining establishments, adopted a "roaming" access model, the subsidized Wi-Fi would likely lead to more business for everyone.
