I'm looking for a solution for backup storage while travelling. The best reviewed device seems to be the Nexto ND2730. I would prefer a device that lets me preview the ORF files. Nexto aren't the best communicators so I haven't been able to find out whether they can, or will support ORF. Any other ones that I have looked at, and there aren't many, seem to get lousy reviews. Has anyone here found a good solution?
