Was this written in the 2000s? "The only problem is, there aren’t any ARM rack-servers or workstations." There have been commercial rack mountable ARM servers for years now. Even the simplest Google search shows a wide range of ARM rack mountable servers. You can even special order them from Dell. What are don't seem to be is great value. I am sure a few netbooks would be better value. (ps re-installing the operating system is not what anyone except maybe ma and pa, would call trashing one).
Googling "Dell ARM Server" shows me a bunch of articles from 2010 about a proof-of-concept.
What do you recommend that people order from Dell, for less than $2000? (Note that the Chromebook in the article retails for ~$200, and IIRC the other ARM boards mentioned are also like ~$100-$300.)
