You may already have a digital camera (still or camcorder)with video or hdmi out which you can plug into a TV or monitor. These have the advantage of zoom and autofocus and often have a power input for continuous use. It's steadier and less tiring to use a tripod or copy stand. For camcorders, see the thread at http://www.avsforum.com/t/1302280/low-cost-cam-with-live-hdmi-pass-through Another choice is to get some strong binocular loupe glasses from China via ebay. They come in a variety of strengths and you can examine or read by moving the material in front of you. They are cheap ($1-50) and portable. Some come with their own LED illuminators.

You have some advice on mirroring/Raid. Be sure to address your points of failure/threat:
HD failure
Use SSD(s) rather than a hard disk, mirrored if possible
Power glitch
Get a UPS or run on a locked-up laptop.
Virus
no internet connection (do not share LAN with any internet-connected PC) + remove USB connections and disable them in OS
Equipment Theft
take daily backups home or to a safety deposit box. Keep 1 for every day of week + 1 for every week + 1 for every month
Lightning or motor surge
good surge supressor(s)
Equipment failure
have duplicates available, immediate for low-cost, at shop for hi-cost; replace failing/old stuff.

Andrew Carnegie and John D.Rockefeller are remembered, usually sans first names, because they gave money away to intellectual causes - Rockefeller grants, Carnegie Libraries, Carnegie hall, Carnegie-Mellon University. They made lots of money keeping down workers' wages and keeping prices high.
But what do you do after you accumulate that pile? How could you spend a billion dollars on yourself? or forty? Time to turn over a new leaf and spend the money making people happy.
But there is no Stephen P. Jobs Foundation anymore. Apple may live on, but Jobs is history.

The Apple][ had an open architecture with 8 open slots. These got filled with memory, z80 processor cards, HD interfaces, and lots more. It spawned an industry. Now Apple is busy selling sizzle rather than protein, gloss rather than substance. But they do sell. There are more rich idiots than geeks.

Currently, integrated circuits like CPUs are fabricated using UV light, wavelength 10^-8m. Gamma rays are 10^-12m long. All other things being equal (but they never are...), this may lead to chips with 10^4*10^4=10^8 more features. This might be worth constructing a 100m long gamma ray lens or two.

Basically, UV, acids, and our atmosphere, especially in cities, is hostile to colours we use in images. Look at the faded signs as well as faded photos. But print on non-acid paper, with inert pigments rather than fragile organic dyes, and keep the air out with a sealed frame or box, and you can expect hundreds of years of stable colour life.
So print it yourself (Canon and Epson have pigment inks on some photo printers) on no-acid paper and matte it under glass (UV protection), keep it out of the sun, and enjoy. (Not against the glass- it will stick. That's why the matte.)
If you're storing photos away, make sure the environment is all non-acidic, too, eg, metal boxes not cardboard or plastic.
Cost-wise, look for processors who advertise no-acid paper and pigment inks.
See http://www.wilhelm-research.com/ for the most comprehensive look.

Life is difficult because it is non-linear.
