Google Voice vs. Whistle; Which is Best?

What we here at Apps for iPads  do not understand is why anyone would settle for Google Voice, which clearly states " While you can’t use your iPod or iPad as a phone" when iPad users can use Whistle, which easily allows you actually use your iPad as a phone, and any call to the continental USA is FREE from anywhere in the WORLD!?  Check out how easy it is to do at http://appsforipads.net/apps-for-ipads/ipad-tips-and-tricks/apps-for-ipads-tips-tricks-turn-your-ipad-into-a-cell-phone NOW! So do YOU use your iPad as a mobile phone?  Which do you prefer? Do you like Whistle (which does not require both  participants to belong to it's service) as much as I do?

Google Voice app now supports iPad & iPod Touch Tuesday, December 14, 2010 | 8:35 AM (cross-posted from the Google Voice Blog) Since we launched Google Voice for iPhone a few weeks ago, we’ve been hard at work to add a few improvements that didn’t make it into the first release. At the top of the list was adding support for iPod Touch and iPad. Starting today, you can download a new version of Google Voice that lets you use all the features of the app on these devices, such as sending and receiving free text messages - except, of course, make cellular calls. While you can’t use your iPod or iPad as a phone, you can use it to initiate Google Voice calls with your phones. We call this feature Click2Call. Simply click any ‘Call’ button in the Google Voice app on your iPod or iPad and then select which of your phones you want to ring. Google Voice will call your phone and then connect your call.  http://bit.ly/gz5Jbw
