I think it's a refreshing OS - at the same time, it's the exact opposite of the OS I have been meddling with (mostly in my head). My ideal OS embodies the core concepts of functional programming and the idea of the traditional web browser is nixed to an extent (the web is a wealth of knowledge but the way it's constructed + modern browsers just make it a distraction factory) - there are better ways of getting data from the web
The OS should help us be more productive - I think we've forgotten what people hoped computing could be 50 years ago. I wish the web were more like a book than one of those free magazines at the car wash, and I wish my OS was more geared towards productivity.
Sometimes a return to explore old concepts is called for. People mock web 1.0 geocities pages but... the information density of the web was amazing back then (hah web 2.0 could really be called the big bang then.. someone already coined the term it seems and has written about the topic at length http://www.emilybinder.com/technology/web-big-bang-and-crunc... it even mentions the 'big crunch'
