Exactly, tiny text on the main screen (if I un-dim it, Immersed dims it automatically). I am not aware of text issues, I guess I never noticed any. There is a mouse emulation mode that is supposed to be more responsive, and native mouse - I use the native setup and don't notice any lag. Just have a good router and be close to it. Retina is the only word I know :) because it started way back on iOS/iPhone before it was that common. And probably because I use a Mac.

One other thing that is an unexpected bonus. It rains where I live. A lot. And when it is grey and dim, I can sit in a "sunny office". In fact, I even tweak my day to the virtual environments. Sunrise in a mountain lodge in the mornings, sunny office or ski chalet in the afternoons. Very positively mood altering.
