That's what I try to say in the article. This is "A" possible future, and it is a first iteration of a totally new product. The first iPhone wasn't a success, and many people were convinced a phone without a keyboard couldn't be the future.
The iPhone 3G was the blockbuster hit. The first iPhone was at best modestly successful. The most obvious indicators were that Apple gave it a significant price drop after 3 months and then introduced another model with more storage after 7 months to bolster sales.
That's actually a good point, and we're currently working at getting rid of this animation for this exact same reason. Sorry if you had a bad experience because of that.
We like using CSS animations as long as they don't hide any content, because we think they create a much more enjoyable experience on our marketing pages. We try to use them only when it makes sense, and in that case, indeed, it does not. Thanks for the feedback.
