I would worry that something breaks after warranty expires and the whole computer can go out of the window. With regular good old desktops you can just replace the broken part. With such special custom made hardware it is sometimes impossible. For example the macbook airs have non standard ssd that is not replaceable, so when the disk dies, whole notebook is done...
Or you can go and get either a warranty extension (before it runs out) or an aftermarket SSD, like millions (including me) have done.
