Since my last post, I got a Dell Mini 9 (1.6GHz Intel Atom N270, 1GB RAM, 16GB SSD) (one of those new netbooks) and loaded my XMonad config from Esteguan, which it does awesomely with.
Then I got a Dell Inspiron 1200 (1.3GHz Intel Celeron M 350, 256MB RAM, 30GB HDD) from a friend. I've installed Xubuntu on it and am planning to do OS development for the computer club at my school.
That same day I brought home an old 486 from my dad's workplace. It has a 66MHz 486, 8MB RAM, and a hard drive of probably less than 1GB. My dad was also planning on throwing out another eMachines 400i that was supposedly broken, but I stopped him and grabbed it. If it's truly broken I might just salvage parts, if not I'll just install a good Linux distro for it.
About a week later my dad asked for a laptop for the new CNC machines so that the machinist can program them using a simple text editor because the built in editor is unintuitive and kinda sucky. So I've given him Esteguan, and taken the DWL-G650 (he won't need it).
Then, yesterday, I was informed that my cousins had an old laptop sitting around. When I visited them I found a Gateway Solo 5300 (700MHz Intel Pentium III, 192MB RAM, 10GB HDD) in near perfect condition. She had used it from 1999-2001 and then let it sit since then, because she wanted something faster (after paying $1600 for it but two years earlier). Also, I found it to be perfectly speedy, then I installed sidux and now it's even faster.
And I don't talk about this one, but I do have another Thinkpad T20 (700MHz Pentium III [Windows lists it inconsistently as 540MHz and 426MHz, but I don't think they sold T20's like that], 128MB RAM, 12GB HDD) but I need it for robotics so I use XP on it. I'm buying more RAM for it now, as XP really really really sucks with 128MB RAM.
Dell Mini Inspiron 9 is named Centrikle, the Inspiron 1200 is Fahrigon, the 486 and the 7th eMachine are yet nameless, the Gateway is named Antikron, and the T20 with XP is named Neezltrak.
