Mylo on trial: $349 and no offline calendar?

I'm curious what folks out there think of Sony's new Mylo, a "personal communicator" that draws much of its usefulness through Skype and the Web. Why would anyone pay $349 for a device that doesn't contain an offline calendar? Even the cheapest iPod Nano, at $149, includes an offline calendar. (Okay, yeah, so it's read-only. But that's good enough for now.)
