If you're in the market for a netbook—the gimpy kittens of the laptop jungle—know this first: on the inside, they're all basically the same. Making the little differences all the more important! And yes, they do add up.
I love the idea of a Vaio netbook, but the only thing that actually gets me going about the first of inevitably many Sony Vaio W netbooks is the 1366x768 10.1-inch screen (which ain't even unique). It's pretty, though.
