    Keeping a notebook docked on this thing cocked at 45 degrees for hours on end CAN'T be good for the hard drive or optical drive. Those drives spin at thousands of revolutions per minute, and the bearings in them must certainly wear unevenly at such an angle.

    I'm thinking that this docking station promotes premature drive failure. Just because this is an official HP product doesn't mean that it won't hurt the PC.

    What do you think?

    Doubtful it would be too terribly bad on the bearings.

    Bearings don't just have a single hard spot on the rollers/balls.needles, so the load is designed to be carried across all surfaces. The entire bearing assembly is hardened steel, and the extremely light weight of the rotating assembly will likely not cause any noticeable, or significant wear. If you actually saw the small roller bearings that support the load of a car going down the road, in completely harsh conditions (unlike the controlled conditions in a computer), with significant intrusion by harsh chemicals/dirt/grime/trash, and consider the external load (outside that of the straight up and down load of the weight of the vehicle) added durring cornering and uneven road surfaces, and so on and so forth, as well as considering the # of revolutions they see in that harsh lifetime you wouldn't sweat the small load offered by the canting of the notebook. Not only all that, but the bearings/bushings in a HD are built to considerably closer tolerances and accuracy then those of wheel bearings, so I say the wear would be.... insignificant.
