Look, the shiny screens are just the first hardware appearance of a tactic that's been a staple of Apple strategy for a long time in the OS "upgrades". Give people a useless feature (or a few) they don't want (or don't even know they don't want because they've never hassled with it before) but will accept for the sake of having the "best" and newest, and then change it later down the road when it proves to be detrimental and annoying to productivity (which they knew it would from the beginning; they do do market research, you know, and know just how far they can push these strategies.)
This way you don't have to rely on mere technological advances to sell new product, but planned obsolescence through simple irritation (in this case, at constant glare) over time.
It didn't use to be this way, but never forget, that, today, Apple IS most definitely a corporate entity that feels they have to engage in such tactics to remain competitive in the marketplace "because everyone else does it." Steve is not making these in his garage anymore.
Is it evil? No. Is it business as usual? Yes. Do we expect more of Apple?
The correct question is should we?
