Mine turned up last week, I extracted a Linux ISO onto a 16GB SD and it worked a treat.
Ordered a 32GB from memorybits a week ago and its still not here
(the 16GB is out of my camera)
What I need to do next is get a screen that takes HDMI or get a DVI adaptor, I had it plugged into my TV for the test.
All in a nice thing to have, I had to wait at least 5 months for it though.
