I have been thinking about getting a wifi capable phone or cell phone that I can use when I travel (fly). I have read that the PSP 2000/3000 has wifi or Skype functionality but haven't heard anyone that uses it for that. Also, I've heard that the new NDSi also has that capability, again don't know anyone that has one. And I just read that if you have a IPod Touch 2d generation model, there is a software program you can load on it and use with a earbud/mic combo to have a wifi phone capability. Have any of you folks had experience with any of this 3 possibilities? It would be pretty useful to be able to have a low cost/ no cost way to talk during airline travel in the airports, etc and maybe plays some games or music while you wait. I appreciate feedback from you guys or gals.
