Fortunately, I have a rather thick skin (and some would say, a thick head)...
Anyhow, I understand the sentiment about marketing. We really didn't do too much to publicize the X4.
Looking back on it, one of the marketers told me we really messed up by pricing the X4 so low. True "Anti-ghosting" is a very high-end feature. The low price confuses people, and they end up comparing it to similarly priced keyboards rather than similarly capable keyboards. We certainly didn't help matters by implying that it is a lesser model than the X6. The truth is that the X4 was originally supposed to be a less expensive model to follow the X6, but when it was in design, we managed to sneak in our new resistive multitouch technology, which really doesn't add much to the cost. We ended up mostly following the original positioning plan, releasing the X4 as a lower-cost gaming keyboard, even though it has this awesome feature that the X6 lacks. Of course, the X6 has features that the X4 lacks, and it is actually more expensive to manufacture. From that perspective, the relative pricing makes sense. But it's still unfortunate that people often miss what a ridiculously good value the X4 really is...
That said, I want to correct one bit of easily confusable marketing. While you can press "up to 26 keys", the reporting structure has limits on the numbers of certain classes of keys. It would be fairer to say that you can press 17 arbitrary keys (not counting the special keys). We have a page up that explains this in excruciating detail:
The 26 is true, but it's not any 26 - it has to be certain types of keys. Of course, it's common in the industry to talk about the max number that can be reported rather than the max number of arbitrary keys that are guaranteed to be reported correctly. That number is 2 for the grand majority of keyboards, including most gaming boards. Many of those high-end mechanical gaming boards are limited to 6 over USB. By this measure, our 17 is awesome.
Finally, to answer an earlier question, the technique we used doesn't actually require a special driver. So the basic functionality works under other operating systems. However, things like macros and media keys require our driver to function correctly.
Hope this helps!
