The colon cleanser was weird because at first I heard a ball rolling around inside and thought "Wow, that'd be messy." But apparently it's just pills...
About the Flips - I'd been using 2 of the rubbery black finish the last couple weeks now, and did a lot of comparisons with the Sanyo Xacti VPC-CG10. It was a bit of a toss-up for me, but in the end I'm happy I chose the Flip. Battery: the included rechargeable lasts 2 hours compared to the Xacti's ~45min, and uses AA's (eneloop performance is also 2hr) compared to the Xacti's proprietary batteries which cost 3x as much and last half as long. The Flip records 8GB (2 hours of HD) while the Xacti requires SDHC cards purchased separately. PQ is very sharp outdoors, with very accurate colors and very fast autofocus/exp compensation. Indoor performance is grainier than the Xacti, but walking around, the Flip pq looked sharper and in focus more.
The Xacti has a flip-out lcd screen, and takes 12MP stills (though it's been speculated they're really more like 10MP effective) and includes a flash. It has a macro mode and has a 5x optical zoom compared to the Flip's no macro and 2x digital-only zoom. It has a manual mode with ISO, shutter, and aperture control, available for both stills and video, but each setting is scattered unintuitively in the menus and it loses the point-and-shoot charm.
The Flip has none of those features, but there is a pretty popular DIY .45x wide angle & macro lens mod available for $22, which I'm happy with (though I'm waiting to superglue it permanently until I'm dead-set on the color).
In the end I favored the Flip for its battery life, picture and overall simplicity.
