You stats: [Assuming "all day" means twelve hours, and that the lifetime is exactly 5 years (including one leap year ;^)>) which is 43,824 hours, then the time you might be without your MacBook Pro is .02738% of the time you've owned it. How onerous. What a burden.] is totally irrelevant to me. I don't care how many years or hours or whatever I don't want to have to bring my computer anywhere if I don't have to.
I really hate in when my phone goes on the blink. I have to have (shudder) people come to my home. I really hate that. It’s worse hsving to take stuff somewhere.
When you consider stuff tends to entropy, I’m faced with more and more stuff breaking down. And I just got a Kindle to boot....
Apple has never kept anyone from doing any sort of repair on their own computers. All they can do is to threaten to void the remaining warranty.
I am a competent technician. When my Macs are out of warranty, I do my own repairs/mods. You claim to be competent: do the same.
I assure you, you won't have to. These are the same idiotic arguments used against the iPods eight years ago... and continuing... that the batteries were not "user replaceable." Within six months of the first iPod being released with its un-user replaceable batteries, there were literally dozens of companies selling replacement batteries along with instructions on how to replace the batteries... a five minute job.. or they would do the job for you for a slight additional, but far lower than Apple's price, fee. Now there are hundreds of such companies. I guaranty that within a few months you will see those same companies offering MacBook Pro replacement battery kits and services.
You will also see Dell, HP and Lenovo notebooks with non-user replaceable batteries as they need to compete with what Apple is offering.
