To add something positive, yes it is a useful device/OS combination. My personal main goal is using the AllJoyn package that is preinstalled along with my own Xbee gateway that I am (very slowly) creating.
The main detractors for me at present are:
1- no drivers from FTDI for the VCP functionality of their FT232 series USB-Serial adapters.
2- Having to rely on SD card as a drive.This is IMO the biggest detractor to commercial scale use.

There are also pre-installed some POS drivers etc, which I have not bothered to find out more about.
I expect that WinIoT development will progress more rapidly now that Windows 10 is released. A published road map would help a lot. MSFT have a long history of supplying embedded products, this is the next version.
