EDIT July 2nd: Saw this review today, it also confirms the previous reviewer's analysis of heat/noise issues this machine generates. Noise can be reduced by replacing the HDD but heat factor would be a different story...
I am not a lenovo basher but before any of you plan on buying this machine, just keep the below fact in mind. Also since it is meant mostly for people on the go so I think considering the pros it has to offer, people on the go will perhaps neglect it.
Heat & Noise
Due to its thinness the X61s can get quite warm, particularly if the room where you are is warm. I also noticed the heat when I was using it at the park and it was over 80 °. It is not too hot to use, but you may find yourself with sweaty palms after awhile. The right palm rest, which I think is where the WiFi card is located, and the underside of the notebook, were the warmest areas. It has one main vent to push out the heat located on the left side. When it gets going, it pushes the air at a brisk pace, which also makes it a bit noisy. The Hitachi 7k100 on the X61s was a bit noisy as well, making the X61s a bit noisier than your average notebook. I personally am not overly sensitive to noise, but I know some are more sensitive. I have used both Hitachi and Seagate 7200RPM hard drives. Some like mine are extremely quiet (I almost never hear mine), while others can be more noisy. It may be hit or miss as to what you'll get.
