1 I fail to see the point of this.  If it were an actual C64 that'd be one thing, but it's an Atom-powered PC built into a crappy keyboard that's missing a bunch of keys.  You can buy a Vic-20 from a top-rated seller on Ebay for $50.  You could probably gut it and drop in your own hardware for less than this will cost.

2 Part of the firmware is a C-64 emulator. In one of its modes of operation, it will act just like a C-64 -- except it will be a whole lot faster. It will run C-64 software.

3 I have no real use for it either, but it's kind of cute in an ugly way.

The Amiga they're promising for later this year might be a different matter; AmigaOS is still in development, even though the hardware has been defunct for many years.  Worst case it looks like a good HTPC.  Though admittedly I don't need an HTPC.

Steven, I think I read that someplace, but it doesn't really change my mind:  There's C64 emulators out there, and there's also real C64s out there, for that matter, and I thought I read the price of this was going to be quite a bit more than an Atom-powered PC should cost (bearing in mind that Lenovo and others sell them for $350.)

I would (almost) never tell someone they shouldn't buy something they want for aesthetic/nostalgic reasons.  I'm just saying this is one of those things that isn't rational to buy.
(OTOH I think the idea of a new Amiga is really neat--when I was a kid I wanted one of those almost as much as I wanted an Atari ST.)
