Lastly, i dont understand the entire "User servicability" issue. why would anyone want to go into their machine and service it? i dont do it with my washing machines, my car engine, my television set, etc. Did it ever occur to anyone that apple is using custom pentalobe screws because they dont want people going into the box with a steak knife trying to pry the battery out and then file a lawsuit against apple because they ended up blowing their eyebrows off?
You dont want to open it up, but the lack of a removable battery or servicable parts is a problem for a lot of people. We dont yet have battery technology that lets the machine run for 12 hours, and if you need to get a whole days work done on the road, you could just sleep the machine and swap out the battery with the older portable Macs. Carrying around a couple of spares wasnt a big deal.
Batteries often under-perform and fail to live up to their advertised spec. Having a problem with the old Macs? Walk into an Apple store, explain the problem, and walk out with a replacement battery.
Now you have to leave the machine with them while they replace the battery. Or maybe they treat it like an iPad now, so they swap out the hard drive and give you a new machine, who knows‽
Or maybe after a couple of years your battery dies, and you just decide to replace the machine because you cant do without one for a couple of weeks waiting for them to swap out the battery?
It absolutely leads to more waste.
And as for upgradability, Im using a MacBook right now that came with a 60GB 5400RPM hard drive, that how has a 120GB SSD inside itSSDs werent even a thing you could buy for it five years ago!
At the time, we could only afford to buy the base-spec machine, and now its been upgraded to 2GB RAM. (maximum it takes) We have another MacBook that got upgraded from 1GB to 4GB at the same time. Both of them were starting to feel very slow, and we were considering replacing them with new machines, but the upgrades have made them fast enough to be useful again.
I've also replaced the optical drive in one of them, which was a half-hour job for me to do, but would have meant sending the machine off to Apple for a couple of weeks and paying
significantly more to get the same job done.
While I was at it, I also cleaned out the fans and applied some better thermal paste, because Apples factory application was very poor and the machine was now running with the fans up high all the time.
Its possibly more expensive in the long-run, but far less wasteful, and cheaper in the short-term to keep them in a useful state, especially if you do it in stages rather than upgrade everything at once.
Over the years, I think Im approaching having had six or seven battery replacements spread over various Apple notebooks. (not counting having spares on-hand) Now I dont know what I would do if the battery fixed inside one of our newer machines died.
