Please report back in the thead that bcn linked to give us your impressions on the Asus T200. That's a very nice hybrid machine that should be a great platform for running OpenCPN
I am glad to hear that it has an internal GPS, as none of the reviews
had mentioned it, and some comments claimed that it did not. But that's a common error because people can't get it to work out-of-the-box with legacy Windows apps (as you discovered). petrsimon's GeolocationTCP utility should fix that for you - let us know so others will benefit. Be patient with getting a first fix. It can take several minutes.
I just picked up an Acer Switch 10 for $229 from MicrosoftStore.com. It does not have internal GPS, though. My Miix2 8" does have internal GPS. It has a lot of quirks, but does work as long as you hold the tablet upside down so that your hand does not cover the antenna
. (I said it has quirks!)
