Just like Star Wars Episode 1, San Fransisco, and guacamole, Unity does not exist in my world. I just refuse to accept it's existance.
Currently, I'm running three linux machines.
My desktop is a 2.8Ghz p4 with a gig of ram, 16gb solid state drive, and 4tb IDE drive (for swap, /tmp, /srv, /var, and /home since those are the partitions that get the most writes, which kills SSD's.) Running Ubuntu 10.04 LTS
My laptop is an old 600mhz with 256mb of ram and a 20gb drive running lubuntu (lxde instead of gnome) The only time I really use it is for service calls to friend's houses to fix their computers. It is a huge help to have ssh and ethereal handy.
The third machine is a VPN/mail/samba/cloud server running ubuntu server 10.04 on a dual processor 2ghz P4 (x2) with 4GB ram, a 16gb ssd, and raid 1+0'd 1tb IDE's. A few weeks ago someone gave me an old MPVPN that had a 4port gigabit NIC in it that I threw in my server and boy has that helped! 4x 10/100/1000 ports plugged into the internet. My files sync almost before I'm through typing the commands.
