Why is it so difficult to buy a surface Pro 2 in Europe?

I live in Malta (part of the EU) and none of the electronic shops on the island sells the Surface Pro 2, or even have pre orders. They all reply that it is not available from their supplier. I then tried buying one (256GB Version) from Mediamarkt, Switzerland, and guess what, after ordering it 4 weeks ago, the surface pro 2 is STILL not available. Apparently it's also out of stock in the Swiss MS store.

My point is this: why isn't Microsoft doing its best to easily supply their devices around the world? Apple devices compared to the rest arrive immediately in stores here in Malta. How does Microsoft expect to compete with Apple if it doesn't solve it's availability problem?
