I have no idea if I'm the Netherlands or Japan for the store. But there's very few apps in there (I get 249 when I search for a blank term).

There are some Dutch apps, but also apparently some Chinese. The only really useful apps are MS's (like OneNote MX) and Kindle.

By the way, if you haven't tried Pinball FX2 (one of MS's games for Windows 8), you should. It's pretty fun, and the one free table (Mars) seems reminiscent of the old space cadet table from Windows 98 with its missions and stuff. The ball physics are a bit wonky though, pretty standard for computer pinball.
