[X4U] Usability test on the Mac Air book - Macintosh Wins

[Ed Gould]

The envelope, please

In the end, the testers found the Apple MacBook Air to be overall the  
most usable of the three ultrathin laptops, although it didn't excel  
in all the tests and categories. The Lenovo ThinkPad X300 was deemed  
the second most usable laptop and the Toshiba Portege R500 came in  
third.

"The MacBook Air has the clear edge over both the Lenovo and the  
Toshiba in terms of usability metrics," said Thornton.

The overall results were extrapolated from three factors. The first  
was the time it took for the testers to execute each of the nine  
tasks. "On average, where there were reliable differences in time,  
participants completed those tasks about a full minute faster using  
the Mac Air," Thornton said.
