IMHO &#x27;the newer Suns&#x27; (as in the pizza box things that are now 2 decades old) always felt slow compared to other boxes I was using at the time. The OpenLook window manager was also a bit naff compared to what else was going.<p>I preferred Silicon Graphics hardware back then, the user interface was as cool and responsive as it gets rather than the juddery OpenLook effort the Sun machines had.<p>I stayed working with SGI machines when the PC&#x27;s started to get really fast - Ghz clock speeds rather than the few hundred Mhz that RISC machines did back then. I felt RISC should have the higher clock speed, but it wasn&#x27;t to be and SGI and other workstations died a death shortly thereafter.<p>During those end times I spke to some SGI engineer who tried to persuade me that it really wasn&#x27;t about clock speed, which was true on SGI as there was a lot you could do in the many hardware boards a typical SGI machine came with. For most actual real work the graphics pipeline would be maxed out with the CPUs (of which there could be many) doing very little.<p>So my Raspberry Pi vs... would be Raspberry Pi vs SGI Onyx &#x27;Infinite Reality&#x27; desk-side super-computer from some time in the mid 1990&#x27;s. These usually cost real money and were tricked out - I had one with 256Mb of RAM and 64Mb of graphics RAM. Nobody had that much memory back then!!! Yet would anyone want the 256Mb PI when there is the 512 Mb version?
