You seem to be saying you hate MSOffice 2010 and, by extension 2013 unless it happens to fix some silly something or other, which you pessimistically believe it hasn't. I can only agree that MSOffice in its current state is a horrible, bloated, and nearly unusable mess. By all means buy it. You won't be disappointed.
I don't hate MSO 2010 so much as some aspects of it. And if those apsects have been fixed in 2013 (as suggested by changes in 2011 compared to 2010), then I could live with it.
Other than that, you're almost completely not very far from the mark. Or at least the postal district in which the mark is located.
