iPhone or iTouch?

What kind of cell phone does your husband have?

My husband will be beginning rotations next year and is considering getting an iPhone or iPod Touch so that he can use that instead of carrying around like 13 different pocket reference books.  He'd much rather download some apps and stuff to access the information.

What do your husbands use?


iPod Touch:

MAJOR PRO:  Wouldn't have to change our cell phone plan and pay for extra data packages like iPhone.

MAJOR CON:  Uses Wi-Fi to access the information, and not all hospitals and places have Wi-Fi, right?


iPhone:

MAJOR PRO:  Access to information and internet everywhere through cell service.

MAJOR CON:  Need to change our cell phone plan and pay more for data package.



We are willing to do either option, but is one better for this use than the other?

Is there another phone or handheld device that's also good for medical reference purposes?

Thanks for your thoughts! :)
