If you were deciding to get a car for the first time, how would you decide to get one custom made?
Wouldn't you try a few "off the lot ones" first to get a feel for what you like/ need/ want? It is very hard to design something custom, or tell someone else how to customize something for you until you have lots of hands on experience. In most fields there aren't that many visionaries who can see what it could be like, if only we could stop doing "abc" and do " XYZ".
Or you can find a company that has built lots of cars and guides you through the process: you will likely get the average view of what works well enough.. and is easily maintained because millions were sold and all the mechanics were trained thoroughly and supported with technical bulletins frequently.
Perhaps buying an EMR is like buying a car. Your first car is an introduction and probably will sustain a few dings and dents as you learn to drive it. 5 years out you know what is possible and migrate to the more complex solution: buying the Mercedes Maybach instead of the Harley Davidson Night Train.
So if all goes well, with EMR's you end up balancing:
* Having a one of a kind that cost a fortune, is hard to maintain- cause you have the only one, but makes your life easier- fits your workflow perfectly and seamlessly.
* paying a commodity level cost, maintained and supported easily in a standard environment with standard protocols with things you have to work around.
