Recently I was having a lot of grief with my wireless keyboard, even on full batteries, so I decided to give up my my wireless input devices for now (I had previously given up on a wireless mouse due to poor responsiveness when the batteries were low).

The additional programmable punch pad looks like a bit of a gimmick, but I might give it a go for games if I can find room on my rather small desk.
