In the first attached picture you can see the cradle powered on. Green light indicator. The light turns on when the cradle is plugged into the USB and always stays on.
The Pearl easily slides into the cradle though you have to make sure the gold plates on the back touches the gold chargers on the cradle or else the Pearl won't start charging.
Now the Pearl looks stylish sitting on the cradle on top of your desk
One downside I thought was that the cradle does not accept the Pearl with a case or skin (See third attachment). So for those with the rubberized case/clear case/silicone cases then you may want to think twice before getting the desktop cradle if you feel it is a hassle to take off the case to charge the Pearl via the desktop cradle.
EDIT: I stand corrected. I did not know I had to remove the insert. Thank you Corey!
But for those that have the invisible skin or no skin at all, this is a sexy alternative to charge your Pearl. I haven't calculated or timed to see if the desktop cradle charges quicker than the mini USB/USB cord that came with the 8100 but I'm assuming that it is the same.
Overall:
4.9 out of 5 Blackberries because I like the rubberized case and would like rather charge the pearl without the hassle of taking off the case, then reapplying the case whenever I go out.
EDIT: Rating has been up-ed to
5 out of 5. This is perfect! I removed the insert and now the Pearl charges WITH the rubberized case. I love it!
