No love for FreeBSD?
I use a mixture of OS - won't be stopping using Windows any time soon, although I'm rather irritated that one home install has managed to trash itself and insist my graphics cards are broken (they are not).
Timeline (aka 'recent documents') sounds like a decent idea, but I'm not fond of the rolling upgrades or the loss of control Windows 10 involves. 8 and prior versions on the other hand, just keep on trucking.
My main system is a combination of Xen, FreeBSD, and Windows. However it currently needs a bit of attention, so a lot of the time I'm booting up my OpenBSD systems. To be honest it does 95% of what I want (web browsing, word processing, spreadsheets, some development), and there are consoles and retro PCs for gaming, etc. The modern system is needed for VR, high end virtualisation, and recent PC games though..
I do like OpenBSD, but I'm not blind to its shortcomings. Binary compatibility doesn't exist. Emulation is less than wonderful (Linux subsystem dropped, no WINE, no Virtualbox or accelerated qemu). Graphics card support is dated and there's no manufacturer driver (closed source) support. No bluetooth, firewire, 802.11ac (802.11n is just about getting there). Such a lovely, integrated, easy and quick to install, and well documented system though.
