Have I finally indulged in the Slim :) and I must say I like it very much. The new design over the old 360 I personally find very successful and most of the time they also hums like a soft kitten, but my higher load for the first time yesterday noticed that the Slim LOUD may be after two days. Me personally it bothers though conditionally, because I have to be considerate of my roommates in the evening, but I would refute just that Slim but SOOO is much quieter than the Xbox 360. Sure most of the time it is quiet but (I do not know what the error was) it can also quite loud rattle. Well and that prices are completely covered for additional memory, we know for a long time. But even that can be bypassed easily. set just a few cheap 32GB USB flash drives, back tuck and can play on the Xbox the required software. Is also hantlicher if you want to take the memory to friends :)
So:
(+) Design (+) Smaller size of the housing and the power supply (+) Very high sensitivity of the touch-sensitive buttons (+/-) Usually low volume, just would not be necessary wenns: D
(-) Real puny memory, some games can be only with additional memory play
Problems with the size of the controller's I can, despite great hands, not confirm it only takes a while until you get used to it. All in all, I would always buy again, although there is still little more would have been possible (power supply, memory).
