Power-sucking Keyboard

Is it my imagination, or has the battery life on my Jornada taken a sharp turn southward since I started using the HP Pocket Keyboard? I saw mine drop to 25% today for I think the first time ever since I've owned the device. Jornada and thumbboard owners: do you see a decrease in juice when the thumbboard is attached? Email me with your impressions, or post on the discussion board.
