Small sensor size in in fact an added value for the Q, apart from the size of the cameras and lenses. This is true as long as the output is good enough for the buyer. It doesn't matter that camera phones can give images equally good (debatable) as no one buy a Q as a cell phone substitute; it is a system camera. The Q can do things practically impossible with larger sensored cameras. Besides, the spacing between the Q, APS and MF diital is perfect so that each system provide large enough differences to not directly compete with each other (FF will mess thing up in this regard in the Pentax system). As the downloded files from the Q (JPEG's) compare favorable with scans (Nikon 9000ED) of 35mm slides shot on Velvia 50 ISO I have, I will argue that the Q is serious tool in its own right. Just imagine where the Q system is ten years from now....
The Q is a design camera. Small sensors add value in the same way the Pentax Auto 110 added value. How'd that work out? APS film = smaller cameras. How'd that go?
Low light small sensor performance sucks. Noisy. Looks obvious in most web-based sharing photos. 1" sensors and above make big headway at ISO 800 to 1600. Smaller sensors....still see it. That is the Achilles' Heel of the Q and all small sensors. To differentiate sensors for dedicated system cameras will need to be 1"+.
The Q has telecentricity. That's a no-brainer. It does well (as do most smaller sensors) in daylight (50 ISO), so comparing to Velvia is a canard so long as you keep the size small, don't crop, and don't care about resolution. Many do care, especially when plunking down $1,000 for the "system".
