The Aerio does seem like a tidy and well-kempt design. I have to say again, the Matrix is too bulky and massive to be on par with the subcompact king company, Suzuki. I love the 2ZZ-GE Celica motor, but its spirit really gets muted out in the Matrix. The Aerio definately has room for improvement, which is either good or bad on your point of view (but for the majority of auto enthusiasts, that's a 'good').
Hope to see some photos of that Aerio on 17"s, and finally, welcome to AF!
