The new Apple wireless (BT) mouse and keyboard have much longer battery life than their predecessors, making them much more useful. But gawd, are they expensive!
Keyboard tip to self: I’ve grown so used to my switched modifier keys (caps lock <–> control) that it annoys the hell out of me to have to use a switched-back keyboard! System Preferences, Keyboard, select BT keyboard from list, Modifier Keys.
Mouse tip to self: System Preferences, Mouse, turn off “More Gestures”. This Spaces crap really makes me dizzy (blame the remnants of BPPV, I guess!).
