Eidorian is smart about this stuff. It's sometimes hard to see where the iSlate will fit into the lineup of potential devices I can leave the house with. With the right syncing and maybe cloud-based solutions, I might not have to give it much thought at the time.
I like this idea, but it's hard for me to get jazzed about it. The Lenovo Hybrid gets to that, but I think it's half a loaf. The whole is actually less than the sum of its parts. My concern would be that unless the dock brought some more processing power (and storage) to the table, why would I want to use a slow(er) ARM-based processor for my computing work? Casual users, sure. And from a "wow" factor standpoint, it's cool and all. Hard to imagine such a thing as an Apple docking station this century. But could happen; we've all seen the
patents.
That's where I'm at, too. I can imagine a middle-road between full-blown OSX and iPhone OSX. Maybe some desktop-class apps will be ported to the iSlate? The ones that make sense.
