I have a few ergo 4000&#x27;s and the build quality is most certainly <i>not</i> crappy, this makes me skeptical about your other grivences.<p>However, I have found that people not used to the tilted + split-key design style find it weird.   And it is a big keyboard.<p>My personal issue with the 4000 is the worthless &quot;zoom&quot; toggle in the middle.   It would be much better as a vertical scroll, or even better as a trackball&#x2F;nub.  Whatever Msft design committee who put the Zoom+Back&#x2F;Forward buttons should be shot.
