This is a fantastic example of how many resources we waste with modern software. Sure it's not packed full of the kind of eye-candy we're used to, but lots of the basics are there, and it's
thousands of times smaller than even OSs used on smart phones.
iOS 8 for example takes up 5 Gigabytes, Windows 10 x64 is 11 Gigabytes.
