[GTX2GvO]

Oh boy. Ooohh boy.

Let's start with my Desktop evolution, sha'll we.

SEVERAL MACHINES
DOS 3.x > old Monochrome with monitor fixed with the PC and ONLY 5.4" Floppy's (no HD)
DOS 5.0 > Monochrome machine With hard disk this time. (can't remember how much)
DOS 6.22 & Win 3.11 > Nice 486 with SVGA monitor. (still exists in mom's room)

Pentium1
Win 95 > Don't know which 95, cause I crashed it in like 20 minutes
DOS 6.22 & Win 3.11 > From the above 486 as a rescue attempt. (was forced to use boot disks though)
Win 95a > Better, but it was still a bootdisk that did the needed booting
Win 95b > Short period, fixed booting by repartitioning the HD (guess MBR) but the machine itself died shortly after.
(prime suspect.. Much more EDO RAM than it could handle)

Pentuim3 (current desktop)
Win 95b > Even a shorter period than above. (I moved the HD's etc. that survived from the P1 into this machine)
Win 98SE > Required patching, updating and several re-installations to properly work. (it Rocked back then.. ehm 2.5 years ago)
Ubuntu 7.04 & win XP pro > Wanted to learn some linux, but I failed miserably at it. (I'm incompatible!! )
Win XP Pro SP2 > Using right now. A tad Sluggish, but no major complaints.

Future
Vista (SP?) > I will probably start using Vista in 2011 or so. And on a New machine.
(Not my current P3 550MHz 320Mb RAM Desktop)

Non-Desktop OS's

Laptop (bought 1.5 years ago)
Win XP home SP2 > It's store bought. It's OEM. I'm not going to change it.
(It's a Celeron M 1.46 GHz 512Mb RAM Acer Aspire 3680 series)

VPC/VirtualBox (on Laptop)
Win 98 SE > To save important Data on my Desktop at that time. (VPC)
DSL(-N) > Tried both flavors of Damn Small Linux. Still have the VHD's (VPC&Vbox)
Ubuntu 7.04 > As a pre-test for my Desktop. It's good enough as long as it's used as a Live CD to play it's native games (Vbox)
Win 3.11 & DOS ? > Just to have good old 3.11 close @ hand again (VPC)
OS/2 v2 > Found some Floppy's for them a few months ago. So I though. "Why not." (VPC)
OS/2 Warp 4 > More stable than v2, just got a bit OS/2 greedy @ that point.
Windows NT4 > Just to try it out.
Windows ME > Ditto

Think that's all of the OS's I went through I guess.
Maybe missed a few VPC/Vbox OS's that aren't worth mentioning. (some Linux LiveCD's come to mind)
