Simply said by the creator of Instapaper:
“Previous-me tried to persuade everyone to switch to my setup, but I now know that it’s not worth the effort. I’ll never know someone else’s requirements, environment, or priorities as well as they do…
You should use whatever works for you. And I no longer have the patience or hubris to convince you what that should be. All I can offer is one data point: what I use, and how it works for me.”

Variation Facts and Fallacies: Digital Photography Review
“The main points are fairly straightforward:
1) Every lens and every camera exhibits slight variations relative to its twins that are detectable, but rarely significant.
2) Variations that wouldn’t make the slightest difference in a print may seem quite different when the numbers are presented in a lens review. And, just because one copy of lens X is sharper than one copy of lens Y, doesn’t mean they all are, or that they all will be in your camera.
3) Occasionally, an acceptable lens mounted to an acceptable camera combine their variations in a way that makes them unacceptable together. The lens may be fine with a different camera, and the camera fine with a different copy of the lens.
4) Really bad, soft, out-of-acceptable range lenses do occur. They are fairly rare though and easy to detect.
5) Camera autofocus is more variable and less accurate than you think.”
“This Lens is Soft”…. « Canon Rumors
Quite enlightening, if you ever wondered why many lens reviewers say that they needed to try 4-5 copies of a lens before they got a proper one. Then again, also makes you slightly paranoid about whether your camera body+lens combo works properly. Summary:
“The mechanical parts that are assembled to form a lens, lens mount, and sensor are going to vary a bit with every lens and every camera.This variation will cause every copy of a lens, and every copy of a camera body, to have slightly different characteristics.A lens may be fine on one camera and not another. A camera may do fine with one lens and not another.Some lenses (and cameras) will be far enough out of spec to just suck, no matter what they are mounted to.It seems logical that ‘bad batches’ can occur because a shipment of one or more parts is defective and not caught during routine testing (or the manufacturer decides it’s cheaper to ‘ship and repair’ than to hold a shipment).When the manufacturer knows about a “bad batch”, they probably identify the problem and correct it for future lenses, but they aren’t going to announce it unless they absolutely have to – when something is so bad it’s affecting overall sales of that item. Roger’s Rule of Problem Announcements: Once its announced that 5% of lens X has a certain problem, 50% of the members of any online forum will announce their lens has the problem. Whether they own lens X or not.Of course future batches aren’t necessarily better, just different. Problem A may have been fixed, but the new supplier of part 32543 may make a bad batch, or the machine tools used to lathe the last set of part 2433 may have become more worn and less accurate.”

The % share picture changes drastically depending on whether you are considering the OS share, revenue share or profit share. Not to mention the kind of product segmentation difference between Apple & the others (Samsung shown as an example here)

A very handy tool (albeit commandline based) that allows you to work with image metadata. You can even extract the metadata to a file for detailed analysis.
Of the musical kind. In case you wondered whether the orchestra conductors just waved in the randomly or not, the techniques section should help clarify any doubts:
“Conducting is a means of communicating artistic directions to performers during a performance. Although there are many formal rules on how to conduct correctly, others are subjective, and a wide variety of different conducting styles exist depending upon the training and sophistication of the conductor. The primary responsibilities of the conductor are to unify performers, set the tempo, execute clear preparations and beats, and to listen critically and shape the sound of the ensemble. Communication is non-verbal during a performance, however in rehearsal frequent interruptions allow directions as to how the music should be played.”
What the Vaio Z says about Sony’s little design problem – Boing Boing
Changing your design with every new launch kind of defeats the purpose of coming out with a good design. This is another area Apple seems to get much better than its competitors. In fact, Apple has stuck to designs inspired from others longer than its original creators.

“Radiosity is a global illumination algorithm used in 3D computer graphics rendering. Radiosity is an application of the finite element method to solving the rendering equation for scenes with purely diffuse surfaces.”
