I feel that the post is a little too harsh based on the fact that this release is just a Consumer Preview and the RTM is still 6 months ahead.
I believe that even though Microsoft has just "metrofied" the start menu, this is still a leap forward in terms of UI.
I understand that Metro apps are still evolving, and this is just the beginning. Wait till we get to see the Marketplace open to developers and some amazing apps being released.
