When I said:
1. User with no Ubuntu knowledge and doesn't want to (or know how to) partition
I did not say that the lack of Ubuntu knowledge implies the inability to partition. I said that a [Wubi] User may have no ubuntu knowledge, and might also not want to partition to find out about Ubuntu, or in fact might not be able to partition at all.
And when I said:
3. Is now able to partition
I did not mean (nor is it reasonable to deduce that I meant) that somehow by way of using Ubuntu with Wubi they have magically come to understand how to partition.
That's what is known as a straw man argument (or at least that's what 5 minutes of google gets you)
