I'm by no means a gamer, but I will occasionally play some Team Fortress or something new every once in a blue moon. I'm getting the i5 variant of the SP3 in the next month or two (in time for the school year) and was wondering about its lifespan. I need the device to last me through the next 5 or 6 years of school. I keep reading reports of heating on the back panel, and in such a small case I worry that over time this heat would hinder the device's longevity. Anyone have any input on this?
