I'm sure the technicians who gave the new MBP a low rating were among the first to order it for themselves.
As other posters have noted with the tight design I say GREAT JOB APPLE.
Out of the 20 years I've owned Macs I've only had one issue and had to have it fixed. This was only because my 2 year old put coins in the CD drive of my iMac. I could have done it myself but I'd rather let someone else do it.
I've talked with iFixit's upper management on subjects like this and kind of laugh at them. They are all about repairability and a better environmental impact, however I'm sure those parts (in other computers, that get good ratings from iFixit) that are being replaced are not recycled at all and get tossed in the trash. I would think they would be encouraging users to take it to the professionals, who can be required to recycle rather than throw it out.
