Gosh, I don't even know what that is.
The idea is really good, But until you can access the internet from absolutely everywhere, It will have its problems. Being able to keep your files and apps online is really good, Because a less powerful, less expensive computer can be used to do the usual things, And your documents are everywhere as long as you are connected.
And if you decided to mess around with the OS like that, Isn't it just going to be easier to change the OS? There are plenty of people who used a different version of Linux, Or installed Windows on it.
For some people sure it would be easier. As I said way back at the beginning of the thread I personally wouldn't do it though. There wouldn't be any need to since the only thing I'd ever likely need developer mode for is something I could code around anyway
EDIT: Just to be clear, that reply was more of a response to calling it a dumb-terminal since I tend to dislike that term when it's used to describe something that isn't one.
