In the beginning, man created the mouse ball, and the two rollers, and the left and right buttons, and the ps2 plugs. Then one day, the LED mouse came, and the old mouse and pad went into the recycle bin.
Eventually, we upgraded the LED mouse to one with higher density scanning, and with a light and a wheel.
I kept this for 4 years, until the cordless mouse with 1800dpi sensitivity invisible led display and 24 month battery lifetime (so they claim). So far, so good.
I do not buy Microsoft stuff, as it is my experience to be undervalued (too expensive for what you get) and under engineered.
My best best keyboard is a wired one from IBM. I got it as soon as the ps2 plug was out. The keytops have curves on them for me, a touch typist, and it helps prevent accidental depressing the adjacent keytop by centering your finger right into the middle of the key.
I have another kind of wireless keyboard, and the friction to depress the keys (not the detent action) is annoying. I am thinking of spraying it with Jig-a-loo to lubricate the keyshafts. My concern is, will I damage the thing. I will test with an older keyboard first, and if it works, I will apply to my daily keyboard on my second system.
Oh, I run Fedora 20 beta on all my systems. One with Gnome, one with Cinnamon, and one with xfce. (8gig with Gnome, 4gig with Cinnamon, and 1gig netbook with xfce).
I use terminal mode for most of my things I do, and then gui for firefox and emails.
