A really excellent, detailed review of the iPad from a user’s point of view.  Just a couple of quick comments on this:

• I totally agree with the iWork comments. I want to save documents somewhere in the cloud, be it iWork.com, on my iDisk, or elsewhere.  Or it would be nice to have a way to wirelessly sync with iWork on the Mac, but I think that’s too hard and clumsy to do.
• In addition to Amazon’s larger collection of books, I can also share my e-Books with the Kindle reader on the Mac or on my iPhone, and use WhisperSync to remember my place when I’m device-hopping. To me, that makes the choice easy - I want it everywhere, not just on one device. (But iBooks IS a much nicer reading experience…)

In fact, the syncing story is the Achilles’ heel of the iPhone/iPad/iPod universe.  It was acceptable back in the day when these devices were new and DRM was king, but now it’s becoming a bit of an anachronism.

Palm had an inadequte-but-better solution with HotSync and Conduits: developers could write a program that plugged into the device synchronization to take application data and sync it with whatever they needed on the desktop (such as a database, or a 3rd party calendar, etc.).  It was cumbersome, and you had to build separate conduits for both the Mac and Windows, but with a little banging it usually worked.  Of course, the cloud is a better story - easier, no extra software to install (hopefully), more reliable (hopefully), easier to use on the fly (hopefully).
