AFAIK, the freely downloadable version of MandrakeMove does not have the capability of saving a "persistent home" or user data. It seems to have that code deleted from it. You apparently have to buy it from Mandrake to get that capability, whereas Knoppix has that capability built-in, for free.

(I couldn't even get the freely downloadable version of MandrakeMove to mount my USB key.)

Anyway, as mcaycedo says, MandrakeMove is aimed at Windows users, if that appeals to you. It has comprehensive on-line documentation that tells you how to use it from a Windows user's perspective. It doesn't seem to have as many applications installed as Knoppix, but it looks really nice and easy to use.
