Not sure why the obsession with OS size. I don't mind having a 1GB OS that has really good functionality vs a 50MB one that has none. I do want size to be a factor for server based images which is a different beast altogether.
While my office has a great connection, my ISP at home is less so, particularly in the up direction. On mobile, pushing 80-200MB up is essentially not going to happen, both because it eats into my data caps quickly, and because mobile latency is such that that's really slow.
