This device in particular:

is appealing. I'd love to see an evolution to the same thing with a CD
burner for less than $100 more (obviously, would need to operate on AC or
car adapter to burn CD's). As this is now, it's a smaller/easier version of
dumping digi-cards onto your laptop, which I consider better but not best
solution. Hard drive and CDR backup is enough for me to sleep OK at night.
Some might need even further backup in the field to sleep well.
