So bought the MBA 13" 4GB version. Love the speed and size. Made me crave more (bigger screen, more power etc). So I ordered to build a 15" MBP. It arrived. I thought I would love it but I am having trouble getting past a couple of issues. For one, my palms/wrists get uncomfortably warm. On the MBA I didn't have this issue. I am running the exact same software (fusion with windows 7). Why is this MBP so dang warm? It's making me want to go back to the MBA. Second issue is it's not nearly as snappy as the MBA. I assume this is because I currently have a 7200 RPM vs. an SSD and that if I swap out and put in the SSD it will start behaving as snappy as the MBA. True? Appreciate any feedback.
