This is beyond odd, my right Command key popped out. Given this is a key I rarely use, and I wasn't using the key when this occurred, this makes me a bit uneasy as to what to expect from this keyboard. The key snaps back in, but if you press the left corner, pops right out again. I don't see anything in there. The illuminated keys should be easy to see on all keys, but both command keys, space bar, delete, tab, return and caps lock do not easily show the light. I'll take my laptop in tomorrow, hopefully they can easily fix this without taking too much apart. Now, I have another 2011 macbook pro here, and you can clearly see the difference. Has anyone ran across the before? Took about 4 years until my wireless keyboard popped a key.
