You are propably used to your K-5, so it wouldn't do good for you if you change that late to the Q. It got an entirely different feeling to it, who will only slow you down. Be fast with the K-5 and spend more time with your mother. ;-)
From my experience in response to the OP's query:
Given the similarities in menu structure and "functional language," the knowledgeable K-5 owner's Q learning curve should be less than 2 days. Two 32mb cards permit 2500 RAW+JPG high quality still captures. Obviously, the overhead (stealth factor, dead weight, support gadget, etc.) difference between the two systems favors the Q.
No doubt a K-5 kit will work just fine. My K-7/K-x kit served me well on my Mediterranean cruise (Venice - Croatia - Montenegro - Santorini - Athens) three years ago. As a result of all that adventure, my only purpose is to suggest that the OP think 'outside the box,' that's all. If I had a do over and the Q had been available (wasn't at the time), I'd be all over it and I'm 70+ years old. Or as the Greeks would say, "Easy... No problem..."
Cheers...
