I missed this earlier, and when I saw someone mention it in passing I didn't clue in.
But our eDGes now have Docs-To-Go 3.0! This has some big improvements, including sync-to-desktop (via USB cable), which I've tried and works. I don't use Docs-To-Go that much, but perhaps those of you who do could comment on the new version.
Seems DataViz itself hasn't officially launched the new version, as it still has the following "sneak peak" page:

Bear in mind that this is a free upgrade for us (we got Version 2.0 for free, too, at a value of about $29.99 per eDGe)
