You're spot-on! Those were 2 that I was interested in. The top one actually has a keyring hole in that black plastic base, but it's such a short drive that it's really meant to leave in a laptop, so it's hard to pop it in and out. The bottom one would be perfect, but the 2 things reviewers said were: 1) it gets really hot, which may make it more prone to crap out, and 2) people complained of slow transfer speeds. I could probably live with both of those (possible) issues, but I wouldn't want it to die on me.
