There is, however, a severe shortcoming inherent to the iWork suite of iPad apps: document syncing between Mac and iPad. It’s a convoluted mess. In short, the only way to edit a document on your iPad that was created on your Mac, or vice versa, is to go through a convoluted multi-step process of exporting, copying, syncing or downloading, and importing.
Ted Landau has copiously documented the entire situation in this article at The Mac Observer. Read it and weep.
John Gruber regarding the insanity that is iWork syncing on the iPad. I was *very* hopeful iWork.com might provide something more akin to a WebDAV style sync instead of a silly 1999 style upload/download service. At the moment dealing with versions is a disaster waiting to happen for me. I am very confident that apple will address this with some serious upgrades to either iWork or Mobile Me, but until then I am really disappointed. Couple that with the inability to edit a google doc in mobile safari and I am looking at a cramped workflow. I want to feel like I live in 2010 with my tools, not a decade ago.
