Well, I'm from Germany and can only describe the situation here, but "bonus" discs really are pretty standard for a long time now. Especially with computer and gaming magazines, although some have abandoned them for online content.
For example, Linux magazines often provide a disc with the software that is reported about in the magazine, and often they're also bootable (rescue systems, latest Debian, whatever) which comes in very handy in case you're system broke down and thus can't get online (happened to me once a few years ago). Other computer magazines' discs have demos, free software and drivers but I've also seen them provide movies (I have no idea why). Luckily the notorious AOL discs have vanished
Gaming magazines also put these discs to good use as some of them put video reviews of games on their discs and that really is useful additional content as often two or three screenshots printed in a magazine just can't transport the experience of a game. Of course the PC targeted magazines also have game demos.
You won't see the blinding speed when you're poking around the main UI or some of Google's apps, as they're occasionally nonresponsive, although screen transitions are a bit more fluid than on other Android tablets.
I wonder when this will finally be solved. Previously, the lag was blamed on poor hardware. With this beast, that excuse really does not hold at all anymore.
I do have a ZFS setup of currently 6 disks and I really recommend buying server-grade HDDs, unless you have set up a monitoring system that tells you whenever a HDD is failing so you can buy a new one.
Until half a year ago I used normal USB HDDs that you can buy everywhere. My experience was that they simply aren't meant to be always on and fail pretty soon. I usually had a failed HDD once every quarter year. It drove me mad. Almost one year ago I started using these HDD docks where you can put two 2,5" or 3,5" HDDs into and bought HDDs that where labeled for server use. After half a year they still ran fine, so each time a normal USB HDD failed I replaced it with another dock. Haven't had a single failure since then. Nice bonus: double the amount of HDDs I can connect to the server (speed isn't so much an issue as space in my case). The solution with these docks with better HDDs costs more at first but turns out to be cheaper in the long run.
Many people are unenthusiastic about their work.
