I think it looks quite good, although a couple of things bother me.
1) It looks a bit fragile - wonder how long it will stand up to general wear and tear?
2) I've just totted up the cost and it is around $390, or around £250-260. For the same money, I could get a chromebook, netbook or even a lower end laptop. Alternatively, I could spend less than half that and get a second user laptop and put an SSD in that with Linux.(Which is what I have done and which flies)
Like I say, it is interesting as a project, but not sure of the practicality of it, or the cost involved.
I agree with you Steve in that it is a little expensive to buildt at around $400 but still a great project for someone that has the money and wants to try it out.
Thought I would post this for all the raspberry pi folks. It a great project for the poeple that like to mod and love the pi. What do you all think?
