Windows 3.1, those were the days.
It's not much more than 10 years ago when my family had a computer running 3.1 with 165 MB of hard drive space. Yes, we were behind the times.
Moved from there to a Hewlett Packard. 333MHz AMD processor (K6-2? something like that?) with 32 MB of RAM and I think a 8 GB hard drive (could have been less). It had Windows 98.
Then I bought a Compaq Presario, 800Mhz PIII, 128 MB RAM and 30 GB hard drive. Windows Me. This was late 2000. Upgraded the OS to XP later on.
Spring 2004, Dell, 3GHz P4, gig of RAM, 120 GB hard drive. Still have it, still running XP.
August 2009, Dell Studio 17 notebook, dual core 2.53Ghz Intel, 64 bit, 4 gigs of RAM, 500 GB hard drive, Vista, soon to be upgraded to 7 when I receive the software from Dell.
