The only controller I have ever been attached to was a Third Party controller for my N64, which had a clear plastic casing so you could see the circuit board. Being made of acrylic plastic, it was horrible to hold and it wasn't even properly moulded and put together (the company justified the shoddy craftsmanship by saying it was "ergonomically designed". Ergonomic my foot, the thing was painful to hold). The buttons were sticky, the rapidfire buttons didn't actually work, and the stick became loose far faster than my other N64 controllers.
BUT IT WAS CLEAR! To my 10 year old brain, that made it the BEST controller.
Apart from that, not really. Controllers are just controllers. As I grow older, I don't even care about consoles anymore - I see my PS3, my Wii and my 360 as just lumps of hardware. I see my PC has just a bunch of hardware. I am attached to certain games, but I have no attachment to moulded bits of plastic with circuitry in them. Consoles, controllers, graphics cards and mice - they're just tools to an end: gaming. As long as they do the job (and they don't always, but most of the time they work), then that's all I care about.
I do like consoles, but I'm not attached to a SPECIFIC console. If my PS3 or my 360 ever die, I wouldn't feel sad. I'd feel angry about having to buy a new one, but your console is just one of millions of identical consoles.
I also can't understand why people get attached to Cars. Or even houses. The only things I'm emotionally attached to are people and living things. I don't even really care about my house on an emotional level - sure I care about HAVING a good house, because I need shelter and a room, but if I could get a better house for free, I'd abandon the one I have in a heartbeat.
Material possessions should only matter if they serve a function. Otherwise, why care? Save your emotions for things that can reciprocate those emotions.
