This is a great product. I have tried multiple sync solutions and this one is the best. It's the most flexible, easiest, and most importantly reliable, stable, and secure solution I have found. Please support these great Mac developers by buying this product, if you need a sync solution you will not be disappointed. I don't buy a lot of cheap shareware kind of products, but this is a real product made by smart developers, not a hack, and it's well worth the price.

One thing I might ask is would it be possible for it to detect and deal with iSync conflicts (for example, if they're both trying to synchronize your Safari prefs or bookmarks)?
