[ale] is USB stick safer than CD-ROM/DVD

[Jeff Hubbs]

I would say that you're better off with the DVDs, stored VERY carefully 
and re-burned every few years (perhaps more than one copy).

The USB stick probably won't have any error correction - a cosmic ray 
strike can easily flip a bit.  It probably can't flip a bit on a DVD, 
but even if it did, the inherent error correction ability in the DVD 
format would almost certainly correct it. 

Just the same, I'd use the USB stick at the same time and use *it* for 
casual reading, not the DVDs.
