Well, my MiniSync came today, and I can't get it to sync.
It seems to charge OK, but I get a Winsock error every time I connect (it connects for a second, then drops out). I'm going to bring my cradle home from work tomorrow, and try again using that (it worked here before), before I raise a big stink with BoxWave.
The jury is still out on this one....
Update: the miniSync seems to work fine at work, but I still get the Winsock error at home, so it doesn't appear to be a hardware problem. So, no real knock on the winSync so far (hopefully, I can figure out the issue and get it to work at home, too).
