Apple getting into the budget segment is a catch 22. It's needed to grow market share and fund developers. On the other hand, it might rile some fanboys that use paying more as a way to compensate.
On the other hand, it'll be a way for Apple to properly differentitate its consumer and pro portable lines (which are extremely blurred right now) i.e.:
- MacBook Pro: Uses fast ultraportable Intel chips, can run both the 'Marzipan' and standard Mac apps, can use bootcamp, prioritises performance a little more than battery life, biggest RAM and SDD options etc.
- 'Macbook'/Consumer - ARM chips only, performance on par with current MacBooks, priorities battery life, runs App Store 'Marzipan' apps only, no bootcamp, keeps the same RAM and SDD options for current MacBooks.
I'll predict that whatever the successor to the Mac mini is (just 'Mac') will have ARM chips & in time, I suspect that we'll see some (if not all) of the iMac range heading to ARM, too (meaning 'in a few years').
