The Porsche Book One came onto the market in spring 2017 at a price of around CHF 2,800. It is based on a Microsoft Surface, but with Porsche design and corresponding components such as i7 2.7GhZ, 16GB Ram and 512GB SSD. The price differences are due to the fact that there are used devices as well as new devices currently for sale. Since I bought such a BookOne second-hand, I can only recommend it - it's cheaper and faster than many a cheap Surface.
