Has anyone else noticed this problem? I don't imagine it will affect everyone, as you have to be typing at least 60 WPM to have the keyboard start skipping keystrokes.

I had a few people test out the illuminated keyboard, and the people who were slower types didn't notice the issue. However, all of the faster types (who type more than 60WPM) were getting dropped letters whenever they typed certain words.
It's almost like the keyboard cannot process the letter "t" at the end of a word if you quickly enter a space afterward, therefore the keyboard simply drops the letter "t" from the output. On the other hand, we were able to replicate the issue with every letter on the keyboard, not just the "t." It seems that the issue can be replicated whenever a user quickly enters a space after a word - and the space causes the dropping of the last letter in the prior word. It just so happens that using words with the apostrophe was the easiest case to pronounce the error.
Do note that I've now tested 4 different keyboards, all from different Best Buy's in the northern Virginia region. I was hoping that these units were from a bad batch of keyboards; however, it appears that input system for the keyboard may just be laggy, and that's why certain keystrokes are getting dropped.

Note that you can't press all three keys of DFG at the same time on most keyboards. If you hold down D and F, G doesn't respond. If you hold F and G, D doesn't respond. If you hold D and G, F doesn't respond. There are many sets of 3 keys that have this happen, just hopefully not on any sets you care about.
Since the matrix layout can vary from keyboard model to model, which 3 keys block each other varies. For example, the MX3200 model is the only Logitech has made that blocks on W+A+Space, making that keyboard not work well for gaming (can't move diagonally forward+left and jump at the same time in many games).
Perhaps the Illuminated Keyboard has this happen on n+'+t, so if you are typing quickly and don't release the N and ' before hitting T, the T isn't read. You can use KeyScan to easily test key combos.
If the problem is Key Blocking, there isn't any solution besides getting a different model.

Unfortunately I've already returned the keyboards, but I will purchase another one just to run this test. If I find out that the "n ' t " keys are blocking each other, I presume that there is no software fix?
Also, would you think that Logitech would release another hardware iteration of this keyboard, given the "n ' t " keys probably aren't a very good combination of keystrokes to be blocking?

I can't help but think that Logitech has already identified the issue, and that is why they're not releasing any more stock to Best Buys or any other online retailers.
