Apple is smart. They are walling their products off so that once you get get the latest features and the latest M1 machines, you can't stop upgrading and spending more and more money.
I, for one, now have an HP Windows computer, and a second Android phone, if and when they allow iMessage on Android (and they will hold off as long as they possibly can) I'm going to stop using Apple products, as they have become too overpriced for me. The iPhone 12 Pro Max will be the last iPhone I buy, at $ 1,298 (with AppleCare). Many other options abound for iMessage, like Signal, WhatsApp.....will simply have my friends and associates who want to CONTINUE to communicate with me, use those apps which are readily available and free. This will be a slight inconvenience, but....
My Android phone is a Motorola One Ace 5G, which retailed for $ 415 including tax. It's a great Android phone, and despite no wireless charging, is good enough for this 73 year old retiree. My Windows machine is an HP Spectre 15" laptop with touch screen!!!! Imagine that. With 16GB RAM, 512 GB solid state drive, at $ 1,499, a comparable Mac would be priced at about $ 2,799 to start, and with AppleCare & dongles and accessories, it would go for over $ 3,700. True, the 16" Macbook Pro has 1TB of storage, but I don't need that.
Ok, so now I am ready for all the haters to call me stupid, and ignorant......go ahead make my day! I'm waiting for it!
