For keyboard:
+ Essential compact than predecessors
+ Split spacebar
+ Nonsensical scroll button has disappeared
+ Write as good as the old, for some getting used to
+ Wireless works well (2.5 meters tested)
+ Works for the most part under Linux
+/- Keypad separately
- No LEDs, not even for Num Lock on Nummerpad
- Function keys or F keys, thanks switcher
- Less special keys
Genial is the size. Real compact and writes as well as the old. Man I need something to get used, because some keys are a little further or closer, but that is after time. The separate number pad has advantages and disadvantages. Advantages are that you can lie in where you like. For example, the left (right-handed) so that you can have a hand on the mouse and the other on the number pad. Bad, because you may not change intiutiv between keypad and keyboard. Therefore see that not only positively. I would prefer the keyboard. Stupid right now is that one hardly has special keys. You have to (etc. volume, pause) decide, as well as by a slide switch for F-keys or special keys. Schllimmer gehts never. Dear little bigger and the buttons now. That's the only bad thing about the good keyboard.
Mouse:
+ Great
+ Back button (awesome!)
+ Horiziontales Scrolling
+ Their ergonomically
- Special keys is not all under Linux
+ The most gets under Linux
+ Wireless works well (2.5 meters tested)
Brilliant! Never had a mix ergo mouse belongings now I ask myself really like so far I could cope with the normal little mouse. If I now realize I like the old famous hands have to cramp. The Back button is awesome. So you can follow something while surfing a link and goes to a button on the mouse back to normal button. No more high to Back button with the mouse or the keyboard. But super to other programs. The Windows key can be under Linux (KDE) not prove. Horizontal scrolling I knew I did not, not bad.
Conclusion:
Except for the mistake with the function keys on the keyboard and the unusual idea of the number pad: Simply brilliant. 4 stars because the function keys are pretty useless for me
