Nice sunday.... i hate my iMac

For the past couple years, every single time I'd visit my grandparents house, my grandmother would always have an assortment of issues with her aging Lenovo 2-in-1 for me to "solve" (the last issue she had was an inability to figure out what "tablet mode" was and called me because she couldn't figure out how to get out of the start menu) .

But for christmas she got an iMac. Because most of the family uses Apple products, and since it should be simpler to use, I most likely won't be the first one she goes to when she has an issue.
So as a devote Linux user, I'm torn: should I be happy I no longer have to answer stupid questions (at least, not as many)? Or saddened that one more poor soul will now be sucked into the Apple ecosystem?

Mind you, I will be turning her old 2-in-1 into a linux server so it can actually be put to some use.

Thinking very VERY seriously about pushing the button on this.

iMac 10-core Xeon W, 64GB DDR4, Radeon Pro Vega 64X, 2TB SSD

$6,727 plus tax $403.62 and then another hundred for shipping before fucking December in 'rona.

Could sign up for Apple Pay and do $600 payments for 12 months 0 APR... shouldn't be too bad of a problem provided the world holds together that long... And if it doesn't, then this is my last computer... and I guess it'd be nice to go into the afterworld with a freshly upgraded rig.

IDK, Please talk some sense into me about how stupid this would be.

Also to factor in... I need to buy a new machine one way or another SOON. Or else I need to wipe my main and be out of commission for at least 3-4 days which could cost me a few grand on its own... and then also still buy a lesser mac for my daughter.

Why an iMac and not a cheese grater similarly priced? If I get the iMac I can give my current iMac to my daughter for school. My old 2015 iMac isn't holding up to my use anymore, but should be fine for a few more years for a high schooler to work on. If I get a cheese grader fine, but factor in at least another $300 for a minimum 27" 2K monitor.

Any reason to even think of a refurb trash can design? Are they too old now?

General thoughts on why this entire rant is retarded? Like. I too dislike Apple, but I need them. It's love/hate. But god if I do this I'm buckling in for the next 5 years... tax write off would be nice I guess.

Can't really back down the specs any because I dual boot windows and do some gaming. Need 2TB so I can give Windows and Mac a TB each (and I still have 8TB external).

Don't really want to go lower than the Vega 64X because even that benchmarks poorly against many cheaper cards... for gaming (but does do better for some other tasks)...

Ugh... talk me into or out of buying another god awful expensive mac.
