An update: I tried out the new USB 3 Dongle and it powers up my DVD RAM drive just fine. I used it to burn a CD last night without issue. The USB 2 ports on my Expansion Sleeve also worked fine for powering up the drive. When I plugged the USB 3 Dongle into the docking port on the Expansion Sleeve I received a warning that the attached USB device was not an Elitepad accessory so I guess the dongle cannot be used with the sleeve on. So, to get USB 3 you need to pull the Elitepad 1000 out of the sleeve to connect the dongle. Now for another interesting observation.... The Lenovo Thinkpad 10 and the Elitepad 1000 share similar guts. A 10.1" IPS panel with the same resolution, the same CPU and GPU SoC, the same RAM, and similar SSD (eMMC). However: Elitepad 1000.........Thinkpad 10 30 WH Battery.........33 WH battery 12 hr run time..........10 hr run time 1.5 lb......................1.3 lb The metal case on the Elitepad may explain the weight difference but operationally the biggest difference is Atmel vs. Wacom digitizer. Does the power requirement of the Wacom system make that much difference? I know this has been speculated on other threads but this is a big difference especailly since reviews are putting the Thinkpad at 7 hrs real world. What I do like about the Thinkpad 10 is that the 128 GB with Win 8.1 Pro can be had for $796 (best price I have found) where the equivalent Elitepad 1000 is $951 (best price I can find). Of course that $150 difference cannot replace the desktop dock and cover let alone the sleeves and aux battery. Lenovo did pull off making a thinner, smaller, and lighter 10.1" so kudos to them!
