the start button just takes you to the damn tile interface - well whats the point of that ? since you could get there by going to screen corner anyway. just don't get it.
i also dont get the disconnects between control panel and the bland blocky 'change PC settings' menu, to do things like add a user. also HATE the way it want a microsoft account by default, you have to go hunting to add a local account. control panel has always been confusing but now its split brain.
also 8.1 installed on bootcamp / macbook pro failed to boot on day 2 with a config error. no amount of repairing / rollback to checkpoint would make it work. had to reinstall, went back to 8.0.
i now use windows less and less - use macos for most things and just sweep across to a windows vm screen when i need visio or microsoft project. when you have the two side by side like this on mac mission control you realise how nasty the windows 8 interface is compared to mac.
