Keyboard-wise, the Power Cover isn't much to write home about. It includes the same shallow keys and undersized trackpad as the original Type Cover, which are passable but suffer in comparison to dedicated laptop keyboards and trackpads.

Typical Microsoft, they miss the mark. They made the default cover slightly better but a follow-on uses the previous generations specs. If the cover currently sold has a back-lit keyboard than the enhanced version should as well.
