Well, your entitled to your opinion.
I want my iMac to still look like an iMac.
If you think this is so cheap to do and make, these would've been created back in 2009 or earlier for iMac users complaining about the gloss screen and glare.
Sure, if you want your iMac to look like it's in a constant state of repair, you could just remove the glass and live with the result.
No one really wants their iMac to look like that!
No one came up with this solution until recently.
I am sure many iMac user still would like a mod that keeps their iMac looking like an iMac, too!
You're paying for the developement and manufacture of the design not necessarily just the costs of the materials.
Same theory when you buy a Mac!
This frame is a precise flush fit. Both on the contours of the frame as well as its thickness.
It's a seamless, and near perfect flush fit.
Just like the original glass is a very smooth, flush fit part.
I worked as a designer and in engineering for 15 years. You think it's so easy to get a piece of steel designed and CNC'd
to an exact smooth and flush fit, both in contour and thickness? I dare you to try this by just making a cardboard or paper template to see exactly how hard it is to exactly duplicate the enclosure contours and exact thickness to get a seamless, flush fitting part.
And oh yeah, ahem...contact paper? Good luck with that! ;)
