I just realized something. I bought the keyboard and mouse I have because of the headset I have.
A long while ago, some years ago I needed a new headset. I bought it Best Buy, and the headset I chose was the Steel Series Actis 7.
And then some time later I needed a new mouse. Well, since I already had the Steel Series software installed, I decided to buy the steel series mouse, so I wouldn't need another piece of software to run.
And then I needed a new keyboard, bought yesterday, and I did the same thing, bought a Steel series keyboard. All because I already had the software installed.
Those smart buggers, getting me to buy their other hardware just because already had their software installed.
