I would be one of those people, but at 1500 dollars, seems a bit steep, for the hardware involved. I just got my Chromebook (ARM, 3G) and I'm amazed at just how well everything runs on it. But I don't think that the Dell is my target anyway, as I'm more of a u-boot, and kernel work is more my area of expertise rather than shoving things off into the cloud.
Kudos to Dell for doing this, hopefully more vendors will follow suit.
