I don’t have to take my computer out and start ’Skype-ing.’ I just turn on my phone

Nokia is one of the biggest makers  of cellphones with Wi-Fi chips.      Some high-profile devices  are equipped with  the short-range wireless       technology, including Apple  Inc.’s iPhone and  some BlackBerry models       from Research in Motion Ltd.     

The G1 Google phone from HTC Corp and T-Mobile also sport a Wi-Fi      chip.

One advantage  that  these  new companies  have  in  competing with       established VoIP  services such  as eBay’s  Skype  and Vonage  is that       old-style Internet calling required users to be  sitting in front of a      computer or hooked up to a laptop to make calls.     

Mobile handsets with Wi-Fi chips free them from their PCs.
