While true, aircraft fatality statistics generally are not split that way.
The 747 is a safe aircraft, but there have been a lot of fatalities associated with it, due to pilot error, terrorism, improper repair/maintenance, etc.
While I agree in terms of modern browser expectations (and books absolutely should not need JavaScript), I think books in HTML makes a lot of sense. HTML was meant for sharing text documents, after all.
Beta it may be, but there's a good amount of software and programming language support. The 64-bit version is amazingly stable, even on the nightly version.
Resource efficiency is a huge one. If you are familiar with the Via Nano: it's a SLOW x86_64 chip (sometimes used in thin clients) that feels about half as fast as older AMD 64 cpu. Haiku feels great on a Via Nano, and it's really storage-space-efficient. Linux distros are slower, and use more storage space (especially important for using an OS on a thin client PC).
I've never seen the appeal of GNOME 3+, the design seems so user-hostile to anyone who has used computers for a while: hiding menus for no reason, having super limited menu options, etc.
The only case where I care about an IPv6 address is for something I actually want to expose to the internet. A temporary address would be quite annoying in that case.
Some 486SX boards are even sillier: There's a soldered 486 SX, and a regular 486 socket, so you can add a socketed 486 SX to your board with a 486 SX. Obviously the point is to be able to add a regular 486 CPU, but it's still amusing.
