It is great if you are a student without a dedicated machine somewhere. I can use any machine with an internet connection and work on my code projects. I haven't used the one in the OP but I do use http://mbed.org/ http://mbed.org/ for embedded development.

When it launched there were fears about lock in, but you can export it to an offline GCC environment any time.
