I tried installing OpenBSD 5.6 with XFCE on a Thinkpad X300, and I didn't have any trouble with the hardware I use, or the base system, in fact everything looks well though out and documented in the manpages. (Gnome works too but it feels quite slow even on Linux)
In the end I switched back to Linux when I encountered trouble with applications from the ports, for example libreoffice dumping core everytime you click somewhere in a spreadsheet.
I did write down all the tweaks/configuration that I've done on the system in an ansible script, and my plan is to try again with the next release, and report some bugs if it still fails.
Bumping datasize-cur in /etc/login.conf up to at least 1024M should prevent the libreoffice crashes. It's quite possible that this limit will be bumped up by default soon as the low default limits keep causing issues with applications like libreoffice and firefox (though for some setups low limits make sense).
