I use a mouse where I could reprogram the buttons. Since I don't use the forward/back buttons that so many mice come with, I reprogrammed mine. Normally, I have them set to enter & escape, which is so convenient in 95% of games and even some apps. When playing Sims 3, I change those buttons to page up/down so I can change floors with the flick of my thumb. I'll take a programmable mouse over a mouse with fancy colours. My mouse has a rechargable battery & wireless support, but I can never remember to keep it charged so its always plugged in and I never use the wireless mode. My old one was wireless with batteries. I don't miss it.
