I have the QX100 and am more than satisfied. On iPhone, Android, Windows Phone, Windows Tablet to use super and a brilliant image quality in any environment. The QX30 should serve as a complement to zoom situations. Unfortunately, the whole thing has two hooks: 1) lets in even dim environment, very good image quality in daylight so after that it is no longer fun. That the QX30 due to their values are not so sensitive to light, like the QX100 is clear to me, but the difference is striking ... and not usable even without comparing the images in twilight and less. 2.) 30 × zoom is great ... just goes to a quality even further down, on the other hand not really clean image can be shot for lack of image stabilization, if you do not use a tripod here. There is no doubt, comes from the high zoom, but it is not really feasible.
