Is the 2020 iMac still worth buying? The 512gb iMac is on sale for $1849 on Amazon, so $150 off. I would wait for the 2021 update, but my only concern is that I will need to use windows from time to time and I keep reading that with the new ones it won’t be possible. I also like the fact that I can upgrade the Ram on the 2020 which by what I’ve read, it may not be possible on the new models. Anybody getting the 2020 iMac instead of waiting for the new model?
My 2015 is still chugging along well enough but I'm sort of with you - the 2020 models are extremely nice, but I'm curious to see what the ARM-based iMacs are like. (Actually, I'd like to get out of the iMacs entirely and am still hopeful for something between the Mac mini and Mac Pro...)
If my 2015 died tomorrow, I'd get a 2020 iMac without a second thought. Here's why:
1) Apple is transitioning to their ARM-based systems and people are worrying about how much longer the Intel-based Macs will receive support, but they still have some higher-end Intel systems to support. Most notably, the Mac Pro is still Intel, and even when they release an ARM-based version (which probably won't happen for another 2-3 years, if not longer) I can't imagine them leaving the system unsupported in three short years. If you're the type of person to hold on to your computer for ten years then sure, you'll probably find yourself unsupported sooner than usual, but if you're on the 4-6 year upgrade cycle as most people seem to be, I imagine you'd be fine.
2) Windows support. It's
going to be fine, as we'll be able to virtualize ARM-based Windows and utilize its x86 emulation, but
right now it's a bit premature to jump into it for "mission-critical" applications. This one probably needs to bake for another year or two.
3) The risks of "version 1" hardware. That's a harsh term for the current ARM chipsets - Apple knows what they're doing as they've been making their own stuff for their mobile devices for quite a while now - but we're already seeing some early teething problems with the recent reports of excessive SSD wear on the M1 Macs. If an ARM-based iMac (or "xMac") comes out and looks really compelling then I'd still get it even in its first version, but the knowledge that new ARM-based systems may present some growing pains is another reason why I'd feel fine getting a 2020 Intel-based iMac.
Long story short, if you either can't wait for the ARM-based system to release, or if you need something that only the Intel system can provide (such as running Windows reliably), this is the year to get another Intel system. Starting next year and with each passing year, it's going to become increasingly difficult to make the case to get the Intel-based system over the ARM-based system.
