I simply don't have time for that on a day to day basis where I need my machines to just work. I need it to work to the extend that I now have a base machine running Windows and with VMWare Workstation installed. All production work is done inside a VM with daily snapshots so I can always go back to before it was broken, and then tackle the issue when I have time for it. If my machine suddenly goes up in smoke, I can restore my production machines on another machine. I never have more downtime than buying a new machine, installing VMWare WS, and restoring my VMs results in.
My biggest problem was multiple monitors. The setup was, and still is, an absolute pain to get working properly with difference screen size and dynamic docking/undocking of a laptop.
Transparency is a dependency of trust. While many components of OS X are open-source, even more are entirely proprietary and opaque, and therefore untrustworthy. Not to mention that Apple is the king of absurdly-long-and-unreadable EULAs.
I don't like the bloat, but I don't see it as more privacy invading than any other system logs.
As this comes out-of-the-box by default, and is in fact a pain to switch off, I compare it to this new windows behavior.
Should we compare syslogd to the new Windows behaviour?
Zeitgeist itself runs with the users privilege (it's not a system daemon, it's started by the user's session), so that hypothetical application could simply log the data itself. There's no leak of information to underprivileged processes.
On similar note, I rememember someone arguing that the baloo/nepomuk db was a security threat, I guess since it makes slightly easier to search among the files on the system for a string like "password".
Both claims are technically true, and in neither case I believe they are practically relevant, neither for security nor for privacy. I was nitpicking, I guess.
Syslogd can be compared to windows event logs.
Ubuntu, on the other hand, does not have such a commitment to free software, and has included Amazon ads in the Unity dash in the past.
