I posted a topic on “In search of a quiet mini-computer” for General Discussion, but realized that the discussions went off topic (see Off-topic Discussion) before I had time to check in until now. There are some very useful comments there, but I find the most important is a reference to an ariticle in The Telegraph of this Saturday (May 9):

which mirrors what I find as a very important use of Raspberry Pi:
“What I saw in Raspberry Pi (model B and later B+) is a little silent-running (to quote E. Upton) computer fast enough for all that browsing (and e_mail) at home as well as for office work, using only a wire-feed for internet, not getting stuck with Wi-Fi (EMF) emissions like with many other computing devices (better yet, Wi-Fi dongles are available for Raspberry Pi when needed but you would know it is there since one has to plug them in first). The use of Raspberry Pi for daily work brought me back to the grad school days (late eighties) in the ability to think and to write, when at that time one had to visit a special computer center for dedicated tasks such data analysis and graphics visualization. For many years with desktop computing, there has not been a single day of work without muscle strains, eye problem, exhaustion and finally burn-out.....”
As to my uneasiness with using Raspberry Pi 2, many suggested that the unit be placed in some kind of (Faraday) shield to see if it helps reduce the tensions I feel. Indeed, it does and I think a more practical solution will be to use a metallic case for the Pi such as:

which I certainly will try next.
Thanks to all for your interests and help!
