Loyalty is important. When it comes to a gaming system it's a real no-brainer, you might get on really well with someone, only to find out they play a different unit to you. Suddenly you start to realise that underneath it all, they smell a bit funny, why? Because the box wired to their tv-set is sleek, shiny and black and yours is bulky and a slightly off-cream colour. Sound familiar? It should, it's been happening since 1982. Only the boxes weren't games consoles, they were home computers.
