Now I had decided on this KB910 Fujitsu.
Arrived and unpacked looked this but first quite high.
Enough has been written here already, so I would like to compare directly the Logitech Illuminated with the Fujitsu KB910.
Typing feel:
Both keyboards act when typing very high.
While the KB910 has a very soft (and actually very quiet) attack, is the Illuminated clear crisp and loud (though still low).
When Illuminated mechanical feedback is to have pressed the keys correctly thus significantly stronger.
At this point it is definitely flavoring and Gewöhungssache which Tastatus is preferred.
However, I was very disturbed one thing at the KB910: While you can even operate perfectly clean at the Illuminated keys
if you caught them at the outer edge, the keys of KB910 terminals at a pressure on the edge every now and then.
You'll quickly notice Especially in the lower left CTRL key.
Appearance:
Without lighting both keyboards are delightful to look at.
With the backlight however, the Logitech Illuminated wins clearly.
The lighting of the KB910 is only quite uniform when viewed from the top of the keyboard, which is rather unusual.
In the usual tip-viewing angle, the Illuminated, the much better.
For the KB910 scores visually but with the special toolbar and the red illuminated fields for Capslock, Num and roles.
Other:
By shorter palm rest the KB910 acts but significantly higher than the Illuminated.
The SetPoint driver for Illuminated displays by default in an overlay on the monitor all special keystrokes (such as Capslock).
This I find very helpful, the KB910 from home but does not offer.
My Conclusion:
The KB910 is definitely the price / value for money and recommended.
The typing feel is buttery soft and in any case a worth trying out.
For an additional cost Illuminated one, however, still get added quite a bit quality.
As far as I am concerned:
I'll send the KB910 back and now yet again order a Illuminated.
Especially the terminals of the keys of KB910, if you meet them on the edge holds between every now unnecessarily.
