I was an early and enthusiastic and paying supporter of this product. But as noted in a reply to my own review below, I have run into a problem with e2Sync. It repeatedly times out in syncing between Entourage & iSync. iSync works great for iCal and Address Book and my Nokia N70. This is clearly an e2Sync issue. I have filed bug reports [over two weeks ago] with the developer, including my email address and cell phone and have heard nothing. Indeed, when I filed a feature request/explanation early after buying the product, months ago, I never heard from them then, either. For now, I cannot recommend this product. To the developers: there is still "a hole in our lives."
