text: is it possible to use wifi anywhere we want just because we have a wifi card?   well...yes...anywhere there is a wireless access point (wap) available.  and now-a-days, this is pretty much anywhere.  go to starbucks, or mcdonalds, or holiday inn....or just a crowded neighborhood and you're bound to find one.  of course, if the wap is secured, you'll need to know the password to connect.  now, the alternative is a wwan card.  this is what verizon and sprint are selling now.  it's a card that goes in your laptop that allows you to connect to their wireless broadband anywhere you can get a cell phone signal.  this will provide much greater coverage, but generally slower speeds.
