Nunez,
I suppose it depends what you want to do with the portable device. I had the good misfortune to have my motherboard go out when I first started with a laptop in my exam room as a point of care device. At that time in 2011 I had the crazy idea my nurse would carry the same type of laptop in the exam room and enter vitals and get the chart all ready for me and I would walk in with my laptop and open the chart and away I would go. But then my motherboard went out on my brand new laptop, then the laptop got lost in the mail after it got fixed, but I had three months to critically analyze how I would want to use the lap top at point of care, because I was using my desktop in my office and taking notes on paper in the exam room.
So I realized I should have gotten my nurse a desktop, which she now has a dual monitored, standing desk (thanks to Sandeep for the dual monitored suggestion). The physical space my nurse inhabits is right next to my two exam rooms and my office so we can talk as well as e-talk to one another to minimize missing things by relying on only one form of conversation.
So to get back to your answer, for me my ideal portable device is something cheap, easy to replace, durable and something I can hook up if it should fail without involving any IT local or AC. Also it needs to be light to carry but yet have a big enough screen for my bifocaled eyes. Two step authentication for security. The surface pro way too expensive IMHO and I like the 14 inch acer chromebook combined with VNC viewer Enterprise version so I can replicate my dual monitored desktop at the point of care in the exam room. I have already replaced two chromebooks since starting out with a heavy, loud, clunky HP elitenotebook in 2011. And of course I drone on endlessly about this, but an HDMI port is a must, so you can mirror the chromebook to a large wall mounted TV via HDMI cord to turn the EHR into a visual interactive tool at point of care. I bet two 24 inch TV's, HDMI cords with 6 inch extenders, wall mounts, the acer chromebook and the Enterprise version VNC viewer, would cost considerably less than the surface pro.
