According to PC World and their tests LENOVO THINKPAD X200 mentioned as the best laptop for traveler. Hmm.. how come? Let us see the criteria focusing on.
Lenovo Thinkpad ran for almost 9 hours for battery life test. Compared to Apple Macbook Air which has less battery life, even though it is lighter than Lenovo? PC World did not mention what application run on the laptop to finish as long as 9 hours battery life.
What I am thinking is you traveler appreciate more to longer battery life than the weight, although this thing is also a consideration point as a portable machine.
