NeXT Computers
Unpopular opinion, NeXT hardware was kinda junk.  It was a 68030 machine released into direct competition SPARC and MIPS chips that were 3x faster.  It had a 2bpp framebuffer (and UI) that would have been really clever and attractive in competition with monochrome workstations of 1986, but frankly when it shipped it looked kinda awful next to the 1MB SVGA cards arriving on the market.  At the OS level, Mach was outrageously primitive for a commercial unix (no shared libraries!).  And the one genuinely unique and innovative feature (the big MO drive) turned out to be a technological dead end.The NeXTStep layer was really the only selling point.  And in hindsight that was enough.  But the hardware itself?  Only barely worth remembering.
