It seems obvious now with the tightly packed thin design that over-heating was going to be an issue - I just naively thought that wouldn't be the case/modern tech heat dissipation would have come on. There is nowhere for the heat to go other than out the very tiny 1mm holes in the top half/around the edges. Was my purchase ill thought out/anyone else? But all the heat seems to concentrated around the quarter section behind the USB port. Left side completely cold, right side - almost too hot to touch. Or do I have a faulty fan - it's on constantly/working but seems to be working wayyy too hard. Such a shameful waste of money but no surprise for new technology - always the bloody way. Perhaps I should concede and go Ipad - thoughts please anyone? Then there's the weird little software glitches, like desktop/icons and one icon in particular refuses to stay where I put it; then on tilt, the window rotates and re sizes to portrait but then when tilting back, it doesn't go back to landscape?? Disappointing for 21st century technology - I expect more. No such thing as official SP3 covers either - only 3rd party and they're only online. It's a bit of a slippery character in more ways than one!
