I think that many of us know that doctors are generally late adopters of technology. So, those who got a PDA or smartphone running Windows Mobile or the original Palm OS are probably still using that same device.
Over the weekend, I got together with several physicians for lunch and dinner. During each meal, we talked about the evolving smartphone market and I saw a few physicians show me that they're still using a Windows Mobile or Palm OS smartphone (like the Treo). Most have switched to the Apple iPhone, RIM BlackBerry, or Google Android. However, some still tend to keep what's familiar and comfortable.
Speaking of smartphones, there are still plenty of physicians out there who are using standalone PDAs. You may still remember those devices (maybe you even had one). When will these doctors switch to a smartphone? Maybe these people are the same ones who are still using paper charts instead of electronic health records (EHRs) in their clinical practice. Doctors are creatures of habit. Plus, they're really busy, so they don't have time to play around with the latest gadgets at Best Buy or the mall. I still meet doctors who tell me that they've never seen or touched an Apple iPad.
