1. In a previous thread a forum member wrote that his 4GB RAM / 128GB storage version of the Surface Pro heats up worryingly even when running programs such as MS Office. He suggested that one should go for the 8GB RAM models of the SP2 if you don't want a disturbing heat build-up on running resource-hungry programs such as heavy-duty games. The same forum member asked whether the new CPU in the SP2 runs cooler. What should one expect in terms of heat build-up from the SP2? Also: is there really a difference between the heat generated by the 4GB and 8GB RAM versions of the SP2 when running resource-hungry programs such as big games? 2. I think (or hope) that a USB 3 port has a firmer grip (and a longer grip-lifetime) than a USB 2 port. If you use a USB 2 port with a USB plug and plug-cable hanging from it regularly, it will lose its original firm grip sooner rather than later and the USB connection will deteriorate. This is particularly true of a laptop with USB ports on the side rather than at the back. The movements of one's hands and arms while typing tend to push and pull on the USB plug cable dangling from the side of the computer. For my Lenovo Y580 I eventually had to build a small supporting "stand" for the USB plug & cable serving my USB hub, because the connection went from good to bad to worse as time passed. I notice that the single USB 3 port on the SP 2 will have a USB plug & cable hanging from and pulling on it whenever used. Will the original firm grip of the USB 3 port in this position last with regular use? One has only one USB port on the SP2. If the grip should wear out, it's going to be a costly welding job fixing a new USB port to the motherboard, I suspect.
