Retina iPad help

Hey guys I just grabed the new iPad yesterday. Loving it so far. The display really changes the feel of the iPad. I don't know how to explain it but it feels more desktop like to me. It's definitely a different experience. I'm having some problems though and I was hoping someone out there who also has the new iPad could help me. In safari when I go to facebook the desktop site the little loading circle on the top left near the wifi signal does not stop loading. The same happens on some other websites that I often view. I'm wondering if it's a safari issue or the device it's self. It doesn't seem to happen when I use chrome on those websites. All in all I'm loving the device. Though the weight difference from the ipad2 to the new is pretty noticeable. I find my hands a bit more fatigued after holding it for a while. And it takes a pretty long time to charge this guy. I'm hoping apple figures out a way to make thenext generation lighter and thinner because you can really feel the weight difference and thickness difference. At least for me. Still love the device regardless, this display is unreal. And wow the dictation works really really good! Would love to hear your feedback. Thanks!
