I like the interface but...
The font choice (really thin) is really poor for non HD/retina displays. Words containing “i”s and “l”s are nearly unreadable. Combinations like “il” or “li” are even worse - impossible to tell apart from a single “i". Even without these letters/combinations readability is pretty poor. I suspect it will look better on my rMPB at home, but it should be at least usable on a normal display - and it’s not.
