My favorite is Microsoft Wedge keyboard because it is larger (30 cm instead of 25), making the PC more comfortable use. Typing is pleasant. Exclusively for mobile use, I would have preferred the Microsoft (with tablet Case) But: - It does not work in dual-boot: two OS, so you have two keyboards - The quality is not as good as this: only the plate supporting the keyboard is made of metal, all the rest is plastic. And that is where we see that the price is exaggerated (same price as the K800). My mini Apple keyboard is much better.
