A BusinessWeek comparison of MacBook Air and Lenovo ThinkPad X300
Many factors go into the choice of a laptop, but if mobility is a top concern the X300 does the best job I have seen of cramming a big screen and a wealth of features into a small, light package. The MacBook does without wireless broadband and a DVD player and I have to say I missed both. With the X300, you can use the broadband radio to grab those last few e-mails while your plane sits on the ground, then pop in a movie for entertainment during a long flight. If I were custom-designing a notebook to make my business travel easier, the ThinkPad X300 would be it.
