I'll be getting my first laptop next week (15" powerbook). I've always been a desktop powermac user, so the wireless wifi thing is all new to me. I was in my local Borders bookstore and noticed a sign stating their was a wireless network there. When I asked about it, they said there was a monthly fee to use it. I asked if all wifi hotspots were like this and he insisted they were. Is this true, or was this employee misinformed? I was under the impression that my powerbook (with airport card) could just hook on to the internet if a wifi signal was present. If this is the case, how do they regulate who has paid the fee? Also, can someone please recommend a wifi finder (the small kind that fits on a keychain) and comment on how useful it is. Thanks!
