Horrible Fonts
Inability to customize menus/folders

I have the same issue and concerns, but my main concern is why on Earth would Microsoft push a platform to its business community users that is half-baked.
Oh, silly me, did I forget greedy Microsoft's mantra [aka Corporate Mission Statement]: Our customers are suckers who pay for a product which is inferior to its predecessor then the same sucker who paid for the product will help us develop the product for free by telling us what is wrong with the product they are paying for which we already know is inferior but it is still nice to have confirmation.
I am jealous of Microsoft's monopoly because if most companies did software development like Microsoft they would be out of business.
