Thinking of all of the computers I've had since 2007, all of them are usable and still in use at least once a week.
2006 era Mac Mini Core Duo 1.66Ghz. Run Windows 7 gave it to my mom. She still uses it.
2009 era Sony Viao - Core Duo 1.66Ghz, 2Gb RAM. Windows 7. My son uses it for Office and MineCraft
2009 Dell Pentium Dusl Core 2Ghz, 4Gb of RAM. It's still my only laptop. The display is 1600x900 and is still better than many cheap laptops. The battery is crap though.
2011 Core 2 Duo 2.66Ghz laptop. My wife's computer. It's still feels fast.
My workhouse is a 3Ghz I3 with 6Gb of RAM. Bought in 2012.
