So it's time to replace my iPad 2. The iPad Air is about $100 more than the iPad 4. Is it really worth the extra $100 to get the iPad Air? I don't really care about the 64-bit processor and boosted speeds. I use it for basic web browsing, YouTube, and email. So really I want to know if the narrowed edges, thinned design, and weight loss is enough reason to pay more.
