I'm a gadget nerd, mostly. And I've always loved the idea of making something run better than it was ever supposed to. Getting Doom to run on my 386SX, running Windows 98 on my 486 (quite well, I might add), sticking a giant turbo on my old Saab and having it outgun V8 Commodores and WRX'es, fitting a 55W HID kit into a crappy old spotlight, having a Mag that puts out 4000 lumens :devil:
Bigger, brighter, faster, better. That's what does it for me.
