Reflecting Surfaces

Of course you probably already know that glare screens such as the one you see are becoming the norm, despite many cries in favor of antireflective screens.

Why? you ask.

It is more expensive to apply a durable antireflective screen. That extra $11.09 is important to the manufacturers.

Sounds reflect too and that's why people can put a lot of effort into room treatments for their studios. Carpets, furniture, and bass traps. Bass traps are interesting because they can fix resonances caused by too-low ceilings, for instance, and reduce unwanted boomy effects that ruin the definition and balance at the low end.

Optical antireflective coatings, and acoustic antireflective surfaces, both often use impedance matching schemes to reduce resonances. Camera lenses have a colorful surface that is a very thin optical impedance matching coating. Uncoated lenses went out before WWII.

So why are we getting glare screens on our macs? Is it a way to improve touch typing, or maybe to keep an eye on that person behind you at Starbucks?

I think the shiney screens suck!

I am using my macbook pro right now and I can tell you that the glossy screen is far more difficult to read.

It is the increasing arrogance of large corporations that dictate what we get, and what we do not. The idea of free market choice is fallacious in the face of large scale concentrated financial and market power such as in the computer industry.
