It's impossible for developers to create every single aspect of the game to absolutely and completely suit every single person who is going to buy it. Parts of the gamae are going to be disliked by the gamers. If Bethesda/Oblivion spent all their time creating every possible option for an alternative to every single little molecule in that game (yay! Hyperbole!) then it would either be even more of a mess than in is now, or it'll get released when no-one even knows what "Fallout" is anymore.
If you ask me, complaining about the Pip-boy because it doesn't really look that cool to you is just plain nit-picky. If you wanted to be able to change everything in the game you should have got a PC so you can mod.
If you've played all the Fallouts before, you should have already formed an opinion on the Pip-boy, and as you dislike the Pip-boy, perhaps a PC version of this game would have been better for you.
I hope this doesn't come across as aggressive or anything. Just makin' a point.
There is a difference here. They don't have to create everything for everyone ~just not assume that everyone's casual about a grandfather RPG IP (and even then, the same would apply to a new IP). The way they designed pipboy causes the left arm of any clothing to be substituted for it when the PC wears the outfit; Power armor adds strength (strength that ends at the elbow of the left arm). PA in FO3/NV is badly 'nerfed' as it is, but this goes against common sense and engineering. The purpose of an exoskeleton is to do all or (or in some cases most) of the work, yet in the FO3/NV armors, if you lifted a heavy object in one, the objects full weight would rest on your elbow joint (where the armor is pushing on you), and overtime (or at any time), it could damage your arm ~not to mention the complete lack of armor protection for the exposed limb.
If you examine the BOS PA, it appears as though the artist had intended the armor to cover the pipboy, but abandoned the idea. (If true, then from experience, I think I know exactly why ~but still; this should not have been done this way IMO).
