Small details that are annoying on a console

[Sogreblute]

Sega CD: I like the Sega CD, but it should have never been made as an add-on. I need my Genesis just to use it.
N64: The controller layout.
Dreamcast: No second analog stick.
Wii U: Not having the entire Wii VC on the EShop.
PS4: No backwards compatibility.
