And Apple is not forcing you to buy a Macbook
Really? When did they start selling Mac OS/Final Cut/Logic for PCs?
Expense? It's cheaper to use windows btw.
Oooh... lets see... maybe you'll be lucky and all the software you're using is subscription-based so you can switch to the windows version for "free", but suppose you're using Logic Pro, or Final Cut pro, and have to go out and buy something like Ableton (nb: you'll need the full-price deluxe version for a fair comparison with Logic) or a Premier Pro sub...? What if you're developing iOS apps in XCode? Then all those other little odds and ends of utility software that you'll need - remember to tot up all of those $25, $50, $99 or $9.99/mo subscriptions, too.
That's still assuming that your
time has no value, because you are going to spend
days re-training yourself to use the new system and
weeks getting back up to speed, especially on complex Pro apps like FCP/Logic (lets avoid forking the argument and assume that the alternatives are
potentially just as good & productive). Then, if you're working in any sort of professional capacity, you'll probably need to maintain a working Mac system
anyway in case you need to access your old projects... or spend more days/weeks migrating them to the new systems (if that's even possible).
So, no, switching OS (in whatever direction) will, for many people, have real re-tooling costs and if you are a "pro" who's time has even notional cash value the lost productivity could easily dwarf a few hundred bucks savings on the hardware.
Now, the way Apple's Mac hardware is going at the moment (you can never be too thin, too light, too fragile or have too few ports) more and more people
are going to reach the point where that cost has to be bourne - but its still a significant hurdle.
Luckily for Apple, though, they're not alone in having undeclared design flaws - try Googling "surface sleep of death"...
