I buy refurbished iMacs whenever I need new desktops.
I buy refurbished Macbooks whenever I need new laptops.
And sometimes I'll buy refurbished iPads too.
I find that refurbished Apple stuff is normally pretty solid. And I save a bundle. We just replaced 5 iMacs at our office a couple of weeks ago. Purchased from
www.MacOfAllTrades.com. We replaced a few of our older 2007/2008 models that were still running. And I recycled one of our 2011 iMacs to a new workstation. The new units are SWEET!
We used to use PC's for our business, but we switched to Mac's about 9 years ago. Switching to Apple has made life easier all the way around. We no longer have to replace computers every couple of years like we used to.
Here's a picture of me setting up a group of the new iMacs...
