^^ That's usually what "kills" a new OS, lack of programs or in the case of OS/2 IBM not being able to market it..
Even if they'd been able to market, it's release coinciding with a big increase in ram prices didn't help things.
Speaking memory for operating systems, was watching and a video earlier on the new Epyc processors from AMD. the 16 and 32 core models have 768MB cache, the 96 core has 1152MB.
The guy doing the video (Patrick from STTH) commented that 768MB is enough to run Windows 7.
Not to mention with the new processors coming out it's pushing prices down on the older models. Strong temptation do upgrade my server but hey I'm the power is included in my rent so don't really have a justification as things are fast enough for me.
