Brother for life.
You bet it. I got one toner refill for like $6 for Brother laser printer which is happily chugging along with factory installed drum after 2600 pages printed during over 6 year period. No DRM, no driver drama, and you know what happens to jet printers with such sporadic usage.
Why downvotes? They are both right, with an exception of MacBooks. Otherwise, you are limited by use cases predicted by the manufacturer, even if it “just works”.
I use both iPhone and MacBook, with the latter mostly as a Unix that, again, “just works”, but I can even go as far as compile whole GNU userspace natively with Gentoo Prefix (one of many options).
