- Not The Simplest - The point of web as an OS was simplicity. No worries about "managing" your computer: installing programs and dealing with files. In reality doing everything through the web it involves workarounds. Bottom line is that iOS & Android have simplified using a computer more.
- Not as good at videos and music.
- Less Powerful - Web apps have goten powerful, but not as powerful as it looked like they would get circa 2009. You still can't do a lot of things with webapps. What if Mick-first-used-a-computer-in-2011 gets an ipod? He needs itunes. What if his daughter wants to skype him?
Bottom line is I don't see why people will want a laptop that does less than their phone.
The window manager is also beautiful and I am hoping the os and ecosystem develop into something I can use for real work.
That wasn't the intended purpose though. These were supposed to be computers for all the people for whom windows is too much computer.
