When I first got this dock, I hooked it up to my TV via HDMI and the picture was flickering on and off. I was concerned my HDMI cable was faulty, but set it aside for the time being just to charge my Thrive. 3 hours later, I came back to it and my Thrive had NOT charged at all -- the battery was stuck at the same level as when I started charging. By this point, I was concerned the dock itself was faulty. But when I took a closer look, I noticed there was a small gap between my HDMI cable's housing and the dock's HDMI port. So I pushed the cable in a bit harder and it clicked right into place; after that, the picture on my TV was rock solid and my Thrive charged as it should while resting in the cradle. Not sure if this was just a coincidence but I've had the dock a couple weeks now and everything has been working fine since.
My Thrive sits securely in the dock but isn't at all difficult to remove like others have reported. I do have to use 2 hands to remove the Thrive, but it doesn't take much force at all to get it out of the dock.
Great Lap Stand
I like placing my Thrive in the dock and then sitting with it in my lap. It keeps the Thrive positioned upright without needing to hold it, making it very easy and convenient to use. Personally, I prefer that my Thrive sits securely in the dock because I wouldn't want a loose connection to cause inadvertent dropouts or minor body movements to cause disconnects while connected to my TV. The dock seems to get a bit warm on the bottom, but no big deal. And my Thrive looks great on the shelf while mounted to this dock.
Thrive's user guide does warn about charging the battery overnight and states excessive charging could diminish battery life. If that's true, then it doesn't bode well for this dock, because it invites one to just leave your tablet in the dock when not in use until it's needed again. But with Thrive's replaceable battery, I think I'll live on the edge and just not worry about it.
I do agree with others, however, that this dock should have come with its own power supply. That, or it should be much cheaper. But Toshiba knows there aren't any other options right now if you want a dock. Personally, I think the dock without the HDMI port is pointless; if you're gonna get one, get it with the HDMI port.
Bottom Line -- overall, I'm happy with the dock and glad I got it. It'll save wear and tear on my Thrive's ports since everything is plugged into the dock instead. I'm docking 1 star for the price and lack of a power supply. Otherwise, I have no complaints and think this a great accessory for my Thrive.
