I just got this for my Tab but discovered that it won't charge it when connected to a PC, downside in my opinion. I was hoping this thing would charge it while cradled connected to a PC. So you still have to charge it using the A/C adapter. You can do all with just the cable it came with, without the cradle. So your essentially paying $50 for an HDMI connection, in which you still need to buy the HDMI cable. Even though it looks nice sitting in the cradle on my desk, I think I may just return this.
