While this looks ok in context in the iPad app, it is not as great in Sublime Text for real coding.
Echoing what I've seen elsewhere, it's a little less usable. For example, comparing to Andale Mono, the line height is taller, for fewer lines on the screen at a given character width.
Despite the taller lines, the letters are thin, and it's hard to track lines or glance quickly for code, as compared to Andale Mono's thicker characters that draw your eye along lines and help you spot your place in the code more readily.
