A fun and easy test for your keyboard's N-Key rollover ability is to hold down both shift keys and try to type in the following:

Many keyboards have limited NKRO ability, most are only 3-key, some claim 3-key bypass. Key registers are often clumped in matrixes around the keyboard and if you hold down several keys, often, other matrixes and keys in them won't register. Post your results and with the keyboard you are using! Microsoft article: http://www.microsoft.com/appliedsciences/AntiGhostingExplained.mspx

===UPDATE===
Some people have replied saying that you should be using CAPS LOCK held down as well to get the most out of this test. If you want to update your tests, please try it again with CAPS LOCK as well.

ABS M1
Logitech Illuminated Keyboard
Logitech UltraX
Enermax Aurora

and a couple of other ones...
 
Already did the DAS, seems fine...

I've never had a keyboard that really gave me issues with typing...

Interesting test, but not really the most telling. Bought this cheap to replace a MS Digital Media Pro keyboard that had serious issues with FPS gaming, could not use A+S+Space or S+D+Space, i.e. no back strafing while jumping, so it went into the bin.

I thought about the mechanical keyboards but just couldn't personally justify the cost.

Appears to kick out the vowels and a bit more.
 
This test is more accurate if you turn on scroll lock, and hold down the caps lock key while doing it.

Turning on scroll lock keeps transient voltages from scrolling through the keyboard, making a more accurate test.

Note that the keyboard on this MBP does not have n-key rollover. You can press around 4-6 keys.
