That doesn't mean it's a gimmick. Again, I implore you to actually look up what "gimmick" means. Just because there's a tradeoff doesn't mean that it's a gimmick. In fact, the very issue that you're talking about is something that is improving from Kaleido 3 to Kaleido 4. So even people that use this argument have something to take note of in this release.

When we went from black & white photography to color photography we also introduced a lot of tradeoffs. Would you have considered color photography a gimmick ?
