use of ipods or iphones/ etc at work to store info

I'm not sure if they are ipod touch or iphone or ???

but does anyone use one of these devices to hold useful information pertinent to nursing?

I'm not even sure if such a device would do this but how wonderful would it be to store lab values, info about common drugs, have a calculator, and valuable phone numbers right at the fingertips?

In the notes section you could make quick notes to yourself to document later..and also record reminders to yourself.

Of course personal info about patients could not be stored but info that you use over and over again could be..

What about loading the training videos of nursing procedures? There are a series of teaching videos on youtube that helps nurses review basic skills..wouldn't that be great to have a virtual coach to refresh how to do something?

Taking it a step further, how about communication with a doctor? Imagine texting a doctor and having them text back an order..we wouldn't have to try to figure out their handwriting ..it would be typed out so there would be no error made from misinterpreting the writing.

The question is, do hospitals and ltc units allow nurses to use these? They would be very valuable for a travel nurse as well, or someone working in home care doing visits.
