I have here my new ibook 12". Normally I have a dsl connection to connect to the internet. But, from what I've read this new ibook can connect to the internet without dsl or modem. I suspect that it will work at Starbucks, but decide to try it here at my apartment in NYC. So, I unhook the dsl connection and fiddle around with some menus about airport and Linksys and wallah! I'm connected to the internet. I really have no idea how this is working, or what I'm doing but it seems to be a very fast solid connection. Can anyone explain or point me to some info about what's going on. Is this connection secure? Is it safe to make credit card transactioins accross it? Am I stealing someone elses bandwidth? Should I cancel my dsl subscription? Are there any other considerations I should be aware of? I can't get over how much the ibook has advanced since my old clamshell, apple is rockin. I bought this computer down at the apple store and a guy there said apple sells a million dollars a day on weekends....incredible for one store.
