Summary: I purchased TWO Bloggies so my wife and I would have a "matching set." (yeah, I know, his/hers is so 1985, but... it was a fun idea). We used them for about a week (recorded our daughters Xmas Band concert and took random photos and videos). Here are my PROs and CONs based upon personal experience: PROS: These are very easy to use and VERY portable and convienient. You can actually toss it into your breast pocket! The camera plugs into your computer via USB.
Summary: I read a gazillion reviews on this product and similar products and finally decided to try the Bloggie Duo and the Bloggie Touch. To start with, the software would not download. I spent an hour and a half on the phone with Adan at Sony tech support to get the software loaded. The "instruction" manual is a tiny piece of paper with pictures and arrows and no (1) (2)... It is unclear what steps go first (do you charge first? download first? turn it on???? ).
Summary: I was very excited to give this guy a shot. It's very attractive, feels well constructed, and Sony is usually very trustworthy. But this is not a good product. The good news is that the camcorder feature, which might be the thing you consider most important, is decent. The sound quality isn't great, but it's fine. The videos are certainly YouTube/blog quality. If that's all you're looking for, you can probably do better, but maybe not at this price point.
