Can it be so? I bought a keyboard from amazon site in Germany, but on arrival I found out that it's with QWERTZ layout so I ordered another one from polish Microsoft site. The moment I started using this polish version, something felt wrong - I just couldn't tell what. Then I checked german version again (still haven't sent back) - trackpad feels completely different (I haven't had SP3 so there's nothing to compare to). I tried to clean trackpad with soft cloth because it feels like it's covered with something, but no, it's just that materials are absolutely different - every time you touch german version it feels cold, like glass. The other one is just plastic. Even keys are smoother on german version. Of course I'm returning this one, just not sure what/where to order so my next keyboard is ok.
