Let's see. 10 years ago was 2010.
I'm a young'un. In 2010 I was 12 years old. My "main rig" was this laptop:
Gateway Solo 1400
Intel Celeron 900 MHz
512 MB SDRAM (I think)
40 GB HDD
S3 Trident graphics
VIA AC'97 sound
Floppy and CD drives
This is the laptop my dad gave me with an install of MS-DOS 5.0 that he dug out of his old floppy disk collection, and taught me programming with Microsoft Quick Basic. I got a ton of mileage out of that thing. It never did graduate from MS-DOS, and I learned everything there was to learn about how to use a command line interface to its full potential. And I never did get that AC'97 sound working in MS-DOS even though it claimed to have Sound Blaster emulation built-in. There was a thread about this recently; somebody figured out how to make it work. I would have liked to have had that when I was 12 years old trying to get sound out of Commander Keen.
These days I am somewhat "richer" in technology.
Primary rig 2020:
Lenovo Thinkcentre thin client (for work + internet)
Intel Core i7-4770
Intel HD Graphics
16 GB DDR3 1600 MHz RAM
512 GB SATA3 SSD
Secondary rig 2020 (used as media center and game PC):
Dell Optiplex 9020
Intel Core i7-4790
nVidia GTX 560 Ti
16 GB DDR3 1600 MHz RAM
256 GB SATA3 SSD
I also have several Thinkpads that I use for laptops, the main one being a T420s which has served me well so far.
World's foremost 486 enjoyer.
