Your comparison of Sony HX30V vs. Sony HX20V

Thanks for your answer. It's not really satisfactory, because you avoid several issues; so I need to insist. The INCOHERENCES remain: How can you sensibly declare a NEWER model with a SUPPLEMENTARY, NEW and PROBABLY useful and futuristic feature (WiFi) as runner-up, and consider the previous model with LESSER features and a HIGHER PRICE as winner, with a thus thoroughly ARBITRARY and CONTRADICTORY number and difference of points, and then crown all this with the ultimate and supreme CONTRADICTION that you are not aware of any important advantages of the older, lesser and on top of all more expensive model in comparison to the newer and cheaper one ??? I'm afraid the responsible editor would need a thefty course in logic. But, fortunately, there is also something positive to remark: I VERY much APPRECIATE your two tutorials "Learn about TRUE RESOLUTION" and "Learn about MEGAPIXELS" and the consequence that you thus give calculated EFFECTIVE resolution figures in your reviews but also relativize the greatly exaggerated mega side of (micro)pixels (i.e. quantity mistaken for quality, as so often, and evermore). BRAVO! Yours sincerely Telemach, Geneva/Switzerland

You're correct on all counts. The current scoring on Snapsort takes a popularity measure into account when comparing cameras. This could easily explain why an older model outscores a newer one (because it's had more time to build popularity). Note that these reviews are not written by a human; it's not trivial to simply add wifi. With higher priority work in the wings, details like wifi end up getting pushed back. But I'm sure we'll support it soon enough.

is wi-fi the only difference between these 2

As stated above WI-Fi and paradoxal the smaller price of HX30V are the only differences between these 2.
