I was so excited to dump my macbook air for the SB and I've been mostly happy with the decision. My biggest gripe is that the keyboard and touchpad randomly stop working. Does anyone else have the following issue? When placing two fingers on the touchpad to scroll, there is a delay in the start of the scrolling. This doesn't always occur, but probably 20% of the time there will be a touchpad delay when lightly sliding two fingers up or down.
