I'm just starting to research this, and I'm a little confused on something. From what I can gather, it sounds like if you have a wireless internet account you can only access it if you're within range (about 1000 feet?) of a "hot spot". And I only found about 10 in my city. So I would have to go to Starbucks or something to actually have internet access. I couldn't just go to the park and surf the net. Is my understanding correct?
