Inteller, could you explain in detail why you think the Att 1520 variant is a crappy device, why PMA Incipio case is a scam or PMA in general?
Most complaints are that the AT&T 1520 is "crappy" relative to other 1520's, not on an absolute sense. The complaints are made because the other 1520 models have double the memory and includes wireless charging.
The (non-economic) cost for the extra 16GB and built-in Qi charging is 3g in mass and 0mm in depth. The Incipio PMA case adds 50g in mass and 5mm to the thickness (that's 58% thicker than the device itself). The "scam" is that is costs AT&T users $50 (list price), 2 oz., and over 3/16" to get back one of the features that AT&T removed.
Look at it another way. Let's say that AT&T supported a rival short-range wireless networking technology called Orangetooth. Because of this, they have Nokia remove Bluetooth from the 1520 and they tell users that an Orangetooth case is coming that will provide functions similar to Bluetooth, that the case adds 24% more weight and 58% more thickness. You'd expect the case cost to be negative since it makes the phone bigger and heavier and still doesn't let it connect with the existing Bluetooth peripherals that you've already got, yet AT&T wants $50 for the Orangetooth case. That's the scam.
I wouldn't replace my car or portable speakers because of Orangetooth and I'm not replacing by five Qi charging pads. I already have an investment in Qi pads and I need to keep them for my other Qi devices (920, Agent smartwatch, etc.).
