Supple Cow, I'm glad to hear more about the Mermaid... I've seen it everywhere, but most people haven't said much about it. Is it very quiet? My new blueberry thingy is cool, but not that quiet... so I might just have to spring for that Mermaid if it comes so highly recommended from you!
It does seem nice and small for traveling.
Pretty N Pink looks okay, though I've always wondered why they made vibes to work on keychains... sure, it's handy, but if anyone sees your keys and asks, would you just say, "Oh, it's my vibe," and leave it at that?
I'd rather keep one in my purse.
There's actually one that's shaped like a lipstick tube, so that would be cool to keep incognito.
I know what you mean about double-teaming... I might have to look into what Gilda said about the rabbit. Gilda, do you have the Rabbit Habit or the Rabbit Pearl? I've been thinking one with an unattached "rabbit" might be better, so it could be moved around, but then that's not really hands-free.
