I looked at that one nice one (mmm the Mobinote DVX-POD 7010) and it's pretty nice, but its not an ipod.
I've been thinking a lot about this an I think I might try and "throw one together". I think it's very possible to make an ipod one, it'll just take some time and money. Both of wich I'm willing to spare if it has to do with a touch screen ipod!
