As an incurable distro hopper with 2 spare partitions and a bunch of virtualbox images. I am wondering what is your best install and how long have you used it.
What is your distro?
How long have you had it installed? ( no re-installs of same distro)
What problems have you over come to keep it?
Can you run all Linux distro community software that we use? ( Steam, Mumble and google talk plugin for Google+)
My main right now is Netrunner ( Ubuntu kde4) My longest was Crunchbang installed a whole 4 months last year.
Used Gnome until #3
came out then switched to KDE4. Sometimes throw in Openbox for fun
2 weeks installed
no problems yet
Runs all software. Ubuntu base and repo's make that easy.
