Cons: high temperature of the bottom of the case, poor battery life
"I bought my x100e back in july 2010. From that time on, the biggest problems are by far that the bottom of the case gets very, very hot to the extend that I cannot stand the laptop on my lap.
Temperature just by touching the case is very high. And when measured (by an infrared thermometer) I get the following readings:
Bottom (where the sink heat and memory slots are located at): Between 42°C and 52°C that means 107.6°F - 125.6°F
Side Vent: Over 52°C / 125.6°F Of course I knew the heat was going to be high, but I didn't expected that high.
In addition to that it is very usual that because of the high temperatures of the cores the computer shuts down from time to time (windows/bios self protection).
Besides that, battery life is not more than 3 hours (that is if you are lucky). I haven't seen the 4 hours mark. Of course if you don't do any activity at all it will last long, but that isn't what I bought my x100e for.
I won't recommend any one to buy the x100e, I would rather wait for the new X120e to see if Lenovv corrects the flaws of the x100e design (running extremely hot and poor battery life).
Even though this topic has been posted in several forums and reviews Lenovo hasn't done any action to solve it or even to address the issue. So as for support other than the usual updates and KB, I would gave them a low rating as well.
I gave low ratings in terms of mobility, design and value because of what was described above."
