Likewise, I have no problem with it (for mouse, trackpad and keyboard, all in all-day use). I'd still prefer wired for anything stationary (keyboard & trackpad in my case), just to eliminate the entirely superfluous batteries. In a world where that option isn't available, however, bluetooth works perfectly well for me.
