Well, until this thread, I'd never even heard of them, & I'm not going to go getting one now. We are still working hard on refining Eldy & its facilities and the last thing I'd want is to be accused of stealing other people's ideas. We are happy with our own ideas, thanks!
Yes, the gap between Eldy & the native GNOME desktop of Linux Mint is big, but that is true of any generic desktop OS. Mint is an attractive, easy, polished OS, and getting better fast - people could do a lot worse, and we regard the fact that machine does not using Micros~1 products as an active boon. Our hope is that some of our users will rapidly gain confidence and understanding of their new machines, and then they'll be able to "lose the training wheels" and thus emboldened learn to use the native OS underneath.
As for support from friends & family... I've been in PC software support for 21 years. I adopted MS Windows at version 2.01. I have fixed more home computers than I can count - plus many thousands of business ones - and one of the single most dangerous things that can happen to a computer is intervention from "a mate who knows about computers". If running Linux keeps helpful, well-meaning but incompetent mates from fiddling, that is a good thing! :-)
On the other hand, of course, anyone with a real clue about PCs and software will go "oh, yes, fine, this is Firefox 3.5 and OpenOffice running under GNOME... no problem." The sort of dabbler who goes "where's the big blue E thing, what's it called..." will probably only make it worse.
If they buy it and really don't like Eldy, well, they're still just PCs. It's perfectly possible to wipe the machine & put Windows 7 on it, or add RAM, a bigger hard disk or whatever you like. It won't be anywhere near as quick afterwards, though. Linux goes like stink on these machines - a full, current, high-end distro, not some cut-down thing. You need a rather better spec to get the best out of Windows: a proper Core2 Duo or Phenom, 2-3GB RAM, 3D card & so on...
