Hello,

UX and UI are different disciplines, UX generally deals with how usable a product is, UI is how it looks. UX and UI do not have to go hand in hand, you can have a highly usable product that is horrible looking (good UX, bad UI), and a product that is a bear to use that looks great (bad UX, good UI).

Personally I'd rather have a product exhibit great UX and be less worried about UI, I can live with things not being pixel perfect if I can move around the interface without struggling. MoI does a great job in most areas when it comes to UX, some industry leading in my opinion. I'd prefer if MoI simply made minor refinements over time to it's UX without sweating over the UI, why fix if it isn't broken?
