How old is your equipment?

My 27" iMac is 5 years old. My daughter has a macbook pro we bought earlier this year that is also about 5 yrs old. She trashed her other one that was about 8 yrs. old. My son has a PC laptop that is about 3 yrs old. He's a senior this year - I just hope it gets him through 'til he graduates in May. He also has a gaming PC he built last fall. My Wacom tablet is about 8 yrs old - they last forever. I also have a 24" cinema display that is about 8 yrs old that doesn't work with Sierra for some reason - so it's now a giant paper weight. And... I have a windows surface. The first one I got at Max 3 or 4 years ago?? About a year ago, my daughter dropped it and I had it replaced.

My everyday notebook is nearly 6 years old. A Dell E6420 bought in December of 2011. Runs Win 7 Pro and has a SSD as the boot drive and 16GBs of RAM.

I have older notebooks that still run, a Dell i8200 bought in January of 2003 (works as good as it did when new but is running XP), a HP I was given that has to be nearly 7-8 years old with a Core 2 Duo CPU. Running Win 7 Pro.

And 2 desktops. My main system I built in early 2011 and have upgraded over the years (CPU, RAM, newer HDDs and SSD) (the one I'm typing this reply on) and the system I had before I built my present main desktop. That one I built in 2006 or 2007. Older one running XP and the newer one running Win 7.

My current Win10 workstation is 2-1/2 years old. 

I do have a super old laptop in a drawer  that can best be described as a door stop.   It has Win XP and IE 7 so it's useless for much except storing text, music and image files.   

My MacBook Pro is late 2011. Vintage because it is a 17" matte screen. You can't get 17" MBPs anymore. All the new laptops have  highly reflective screen so the 17" one is good for working with photography. The internal hard drive now has a SSD, the mother board and trackpad have been replaced. The video card was updated with the Mother Board. I'll keep it running as long as I can.

My daughter just inherited my last laptop (Sonicmaster s500c touchscreen NOV 2013) because the Win7 Emachine I handed down before that finally gave up and died but most people get 2-3 years from a laptop and 6 months from a phone
