I think its a good idea to keep the smart watch as simple as possible, especially as it allows for the use of only a few Bluetooth packets, which is enough for about a week. Now if only they could get the device to charge wirelessly....s.
If healthcare apps are on the table simplicity would seem to be impossible to retain. Security requirements and other medical standards would seem to be the issue unless the watch is just a gateway to a central medical 'server' in the home. Maybe thats the best way to go.
I'm thrilled that the Kickstarter campaign was so successful - and that the cost estimations for the device were correct. If a Kickstarter campaign is a loss leader market test or the materials costs are slightly off then such a "windfall" of orders could prove to be a success disaster. Well done.
