Generally, this notebook has a very good Leisung! What is of course negative notice the "lame" hard disk for example, is responsible for ensuring that you can not burn with approximately 8xDVDs. With me 4x worked without problems - is set wenns faster then passes through a buffer underrun (of not however but aborts to significantly higher burning time). Very good contrast is the X700! I would not have dared to dream that 3D performance can be achieved with a mobile graphics card ... the latest demos of various shooters and simulations run phenomenally well! 1A! As for me also the silent mode is excited by whom we may let the notebook run overnight! And to be honest - I've read a lot and some think that the hard drive is annoying - when you hear this and it bothers you, then there is no computer to you do not listen! This notebook is so quiet that you can not hear sounds serious! What I am for left-handed is positive think that the waste heat is discharged to the left and so my mouse hand is always Stay warm;) What I regard as negative is that you can pretty much always has his hands when writing on the boxes. Thus, that sounds plenty modestly if you like to hear a little music in office work. Conclusion: For the money (I paid in 1199), there is no serious alternative to this notebook!
