Having what I consider to be extreme issues using this device with a Linux Netbook. In the span of 3 days, using a clean installation of Ubuntu 11.04, I managed to consume almost 3 GB of my data plan without streaming video or music in less than 3 days. Some could be readily attributable to installing applications over the device, but not the majority.
As an example of the amount of traffic being generated, I just performed a test of booting the device, connecting the netbook to the network and nothing more. In less than 5 minutes, my usage log showed 136 MB of traffic, much of it over port 443 and DNS requests.
Any thoughts/suggestions? I'm within my 14 day return window and am on the verge of returning it based on this kind of usage.
