Having beta tested their WinMo & BB sync software I highly recommend staying away from Mark/Space.
They focus too much on spreading code among several products and none completely focused specifically for the BlackBerry. In fact their resolve to problems is to cripple your BlackBerry rather than update their software. In addition to that, the information posted as a "fix" is often wrong.
Again, I'd stay away from Mark/Space!
