Alemum, I totally agree with you. I fell for the marketing ploy, sat there with my Facebook account open, watched the YouTube video, while thinking to myself the entire time that I was falling for the hype. They are very clever, making nappies like iPhones, getting people all excited for something so... dull. And ethically, isn't the point of cloth nappying to reduce waste and consumption? By continually introducing new versions, they are getting people to buy new ones and fall into a consumerist trap.
That being said, I have one BG v3 which I love but is getting too small for my little girl. It really does work well. So, like the rest of the masses I just ordered a couple of the new ones (we're going to the US next week, so they will be shipped to my mother's house there) because they are bigger. All the while thinking that if I were really serious about reducing our impact on the earth I would be using our old fitteds, or terries. Sigh.
