It’s being about a year now that I have a Fujistsu Siemens LifeBook E4010 as notebook for my work. While I am satisfied by the performance of the laptop (notice that the original 5400 rpm harddisk was replaced by a faster 7200 rpm), the built-in wifi, and very pleased by the large TFT screen (very convenient for coding), the robustness is not there. The plastic tab on the top of the screen to keep locked broke after a few month, but more scary, after a year of travels 3 screws are missing and the rotation axe of the screen is no more stable. A minor disavantage is the medium life time of the battery, you would need a secondary battery would you plan to work all the time during a transatlantic flight. Regarding power, another annoyance is that under heavy CPU stress (such as compiling, gaming) the power supply heat too much and sometimes stops working, not able to work for a long period of time (which you typically notice when the battery fade away also, and them you are stucked). It is heavy too, and not appropriate to cary along all the day.
While this laptop is very nice as transportable workstation, it is not appropriate nor robust enough for frequent travels.
