Might be interesting to find out what your current setup is - photos even better (although my current setup is temporary as we are in transition accommodation so none from me yet).
I’m using as our main machine a mid-2012 Retina MacBookj Pro, powering a 27 inch Thunderbolt Display, Apple Keyboard, Generic Wireless Mouse, and the external drive setup I’ve described in this thread: Thunderbold RAID 5 Promise Pegasus 4 x 1 Tb array, 3 Tb Lacie External Thunderbolt Drive.
I also have an ATV3, iPhone 6S+, iPad4. For work I use an SP3.
My wife has a 2015 Gold MacBook.
The kids have an iPod Touch 5th Gen, iPad 2.
What about you?
