3 options are enough for confusing anyone. I was consfused when I first tried all the 3 options, all have their pro and cons, so why did I finally choose the Flip Mino HD? Basicly for the brand, the design, size and of course the software (made also for Mac!) .
If you are a person that only wants a good camera to record videos with friends, then any choice it’s a good choice. Honestly, all cameras have good quality, sound and are easy to use. The Vado HD is known for having better image quality than the others (a little bit), it also very portable (almost the same size as the Flip Mino HD) and has good software. The downsize? Ugly design and difficulty to control the buttons.
The Kodak Zi6 is also a very good option. It’s chepear than the others and has a bigger screen. The bad thing is that the software included is not that good, and, because of the size, is not very comfortable to carry in your pockets.
Like I told you before, all options are good options. So think wisely and buy your minicamera!
