I'll bet I have read most of the posts on protective covers, films, and cases that are so talked about on this and other forums.
Do we ever stop and think about all the extra money we are spending on this stuff.
I think Apple had it right to offer a simple, but elegant Smart Cover. The key in my mind was not the display protection ... rather it is slick way to turn it on and off, automatically when we open and close the cover. Just a simple magnet. The other is a convenient stand.
Apple already did several things:
First the glass is super tough, and scratch resistant.
Second, they added a coating to make it easy to wipe off finger prints
That's it folks.
Sure, the aluminum case will scratch, and the thin armor skins are good on the back. But, do you really need more?
When you work in Retail you quickly learn to sell the accessories ... that's where the profit is. So it is sell, sell, sell. So they get you to worry, worry, worry. Then you buy, buy, buy.
First off, the so-called thin films over the display actually reduce the touch sensitivity (certainly can't make it better)
Next, it has to interfere with the display quality ... the picture gets diffused through another substrate ... it can only degrade the image.
Finally, it is not cost effective. It is just plain good enough as it is. IMHO.
Sure I can make a case where the add-on film saved the day. If I don't others certainly will ... they do ... they have ... and everyone is in a tizzy.
It is just overkill, and they are getting y'all to part with a lot of money.
Tis your choice. As always. Just think about it. Choices, choices, decisions! I like KISS.
