I've just downloaded and run the current update from the Elonex site successfully.
The device has updated from System version 0.35 to 0.41.
Update process itself was very straightforward (took just long enough for me to to start thinking it had gone wrong though)
The new version has tweaked the interface somewhat. The main menu has some changes with a new Digital Editions entry for DRMed books.
Most significantly the default font seems to have shrunk somewhat, with a book that was previously 800-odd pages on the smallest font now coming in at 600.
It'll be interesting to see what the update in early Feb brings to the device
