Like Windows 7? Nothing competes with Windows better than Windows.
well, I am thinking about an OS based on managed code. Really strong siloing of apps so no such thing as a virus. Much better problem determination features, where I can freeze the system and examine in depth what a process is doing. My superior OS would be well documented with a lot of sample code for every interface. I am sure W8 is better, but W7 is very slow to start. You have to do better at that. The windows shell, at least from a programmer's perspective could be a lot better. Copy/paste between apps is so useful, you have to be able to do a lot more with that. IE could be much better - save everything I browse to, enable me to skip advertisements in videos. Favorites are nice, but do you really need superior hierarchical organizational skills to know how to store a favorite so you can find it at a later time?
