Yes, sold my 27” late 2015 iMac a week ago, so far so good.Just a question: do you use the iPad 12,9” along the MK instead of a Mac? I ask this because for about a year I had a 12.9" iPad along with the Magic Keyboard but I actually used the tablet without a keyboard 99% of the time since when I needed a physical keyboard I preferred to use the Mac. On the go the iPad + MK combination was too heavy so in the end I decided to sell both the 12.9” iPad and the MK to buy an 11" one to use only as a tablet and use the Mac as a desktop computer.
I also use it with no case and and also have the black apple folio. Depends on use case.
When i go away for work etc it goes in my vertical STM laptop bag i have had for years.
