It uses a flash drive, and there is no optical disk. No added-on rubbish like a camera, ect.
The OS is not a file system such as OSX. Therefore, there is not major stress of reading and writing all the time. Which causes major heating.
Among other things which just are not present in the iPad OS.
That is the beauty of this OS, and people complaining and wanting a file-system ect are **** wits who know nothing.
I certainly hope Apple stays obstinate, otherwise all these ignorant pricks will ruin what is a great device for people that know-what-is-what.
