We recently went live with an EMR (Electronic medical record) at our hospital. As slick as the EMR is, it is written for a keyboard and a mouse. Guess what the docs want, you guessed it; Can we get it work on an IPAD? Oh yes, while technically possible via Citrix it is about as about as practical as mounting a steering wheel on a horse. Can't you teach the horse to respect the steering wheel? Um, no.
We have tried tablets in the past for the EMR. The users get excited about them and once they have them, they collect dust. $2,000.00 state of the art spill proof made especially for hospital settings tablet PC's which never leave their docking bays. What a waste.
All tablets are currently toys, iPad included. If I want toy to play with and have an extra couple hundred bucks burning a whole in my pocket then maybe I will buy one, but why would I want a toy with limitations, like the iPad?
Tablets may some day be a respectable tool for some apps who's developers are willing to write to them, but that will be 10 years out. Then, they will be about as sexy as a Palm is today.
