Before this gets into a Geek Slug Fest....
The SP3 is designed as a disposable machine, with 3-5 year shelf life with proper care, it is a closed system and you will not be able to do traditional maintenance, those who are used to user serviceable or even neighborhood computer repair shop help are out of luck.
The good news for most of us we will buy the SP4 and the SP5, etc... so we will never experience the long slow death of our machines.
All of the Surfaces that are repaired are repaired in Clean Rooms using very specialized equipment and then are sent back out as refurb units....
