I am still in the healthcare space (I design hospitals and their networks/datacenters etc) and am currently doing SFGH in San Francisco.
I believe in the idea (obviously) -- but there are still a great number of hurdles to overcome to get hospitals to adopt tablets (especially iPad).
I am working on a pivot of Contineo, that could also work with DR Chrono - and am talking to several facilities about pilots -- but most everyone is taking it slow to adopt iPads due to Apples large % of revenue, the supportability - lack of control etc.
I am building a health care platform for android at the moment - I'd be interested in knowing what Dr Chrono has to give up to Apple... I haven't looked at their business model too closely - but the market is ripe for change.
