Not 90%, but the idea that mITX and mATX are inferior to full ATX is still very much present, although it is changing at a faster pace than ever, I think. Just recently a friend of mine asked for some help about building a new computer similar to the one I'm building, but saying he wanted it to be "normal sized" because he wanted to play games on it. He's not completely computer illiterate either, he just assumed that mITX has compromises in terms of performance and didn't believe me when I told him that it's no different than an ATX board unless he needs more than one PCIe slot or more RAM, for example. People seem to think that computer size is related to computer power. And try to convince North Americans especially that that's not true, they who always love everything that is BIG!
