To clear any confusion
I think the dimensions of his case are wrong, because you can notibly tell from the cover above it
The Imandix 3D case seems to be thicker than other's previews. Not the cover itself =P
That's probably it. Imadix has a lot of different case sizes to choose from, some are thicker which is probably what's causing the letters to appear wider. Here's a stock photo of the original, you can really notice the difference on the "N"

Not that it's a big deal or anything. I just figured this is one of the few sites on the net where we can really appreciate perfectionism, or closeness to it
The cover is great though, I really like the screenshot arrangement on the back. Great stuff! I'll be printing this one off for sure once it goes up.
