I purchased my R4 in August and now I have just received one that I bought for my girlfriend and I noticed a few changes that were made on it. First and most important was the charger difference. It is much lighter and smaller. Although it doesn't have the blue light it is a good alternative for the old larger one. Even though it is smaller the drop in amp is not that much and probably won't be noticeable. Also they have finally accepted the fact that people are going to want windows 8 soon. So what they did was change the windows icon to the new windows 8 icon. How do you feel about these changes?
