Well, I've got them on the SD, and two different HDDs in different computers, and (as of this past weekend) on Flickr. When I get 16GB worth (not insanely far off, with 12MP jpgs and 1280x720 video), I'll work out some permanent archival method; maybe an off-line HDD or two, or maybe DVDs. (I'm not really sure whether I trust magnetic particles or opto-sensitive chemicals more...)

My burning needs are pretty well covered by internal burners in my laptop and both desktops, so I don't have that laying around. Bet I got you beat for 'scopes though! (I have two, which is two more than most geeks.)
