I have three computers and a tablet. I run Linux on all of them. I have one dual booting with Mac OSX. I really hate OS X though. These days, Linux is a dream to use and is infinitely configurable. I plan to update this post with screenshots, and more details in the near future.
2005 IBM Thinkpad t42 running a work in progress Distro of my own manufacture. It has 2 gb of ram, Pentium M processor, 80gb of HD space, and a terrible dying battery. It basically needs to be plugged in to be useful. Thinkpads have been used on the International Space Station, a fact which attests to their reliability.
2005 Dell Inspiron 2200 running #! Statler. It has 1256mb of ram, a Pentium M processor, 40gb of HD space. It’s very comparable to the Thinkpad and I use it as my work computer, with slightly inferior build quality.
2012 Nexus 7 32gb running Android 4.2.
My first computer was a Tandy running Windows 3.1
After that I used a Gateway 2000 with Windows 95
Then I used a Dell Desktop with Windows XP.
2001 Toshiba Satellite 3000-504 running #! Statler. It has 256mb of ram, 1 ghz Pentium M processor, 20gb of HD space. It also has a removable floppy drive that I can switch out for the DVD-rom optical drive, kinda cool but useless feature. It also needs a plug-in wireless card as it doesn’t have built-in wireless. The Toshiba motherboard runs a very Linux-unfriendly bios, as such I can only run the thing with acpi=off. Sold to hard-off for 300 yen, not a bad deal.
2005 (?) Dell Inspiron 6000. 2gb of ram, high resolution screen that is dying with many lines of dead pixels. Dual-booting Windows XP SP3 and #! Statler. Was a really nice laptop until the monitor started dying. Battery doesn’t charge either. I ditched it to hard-off for 500 yen. No more Planescape until I get it working in Wine or GemRB now though…
