World's thinnest smartphone is not ideal for medical professionals
The Nokia E71x is currently the world's thinnest smartphone and it's available on the AT&T network. However, it's not an ideal smartphone for medical professionals because this device runs Symbian S60 3.2 and you'll have a very difficult time finding medical apps for Symbian. Nokia has a loyalty to Symbian, but I have to predict that Nokia will have to branch out into Android if they plan to survive in the smartphone space.
So, although the E71x looks great, it's really not an ideal for health care professionals and students who want to leverage the smartphone in the clinical setting.
