TIME IS NOT THE ONLY TEST

One of the things that made the XR-1 such a great piece of technology was the fact that it is just as much a tool as it was tech.  The physicality of the product had to undergo some of the most grueling environmental challenges imaginable - in service of creating a machine that can perform millions of calculations a second while being submerged in bleach, dropped from a helicopter, or whatever kind of insane punishment you can think of.  Every micron of this enclosure is packed with shockmounted drives, seam-sealed IO, an assortment of antenna and transmissive tech (Satellite broadband, Wi-fi, bluetooth, etc) which far outstrips what one would typically expect from a computer.
