text: This technology may be great and all but the only downside is that you can not have it on your laptop, the text states, "Your home PC can't handles the complex algorithms used to decode Mona Lisa's smile." This has some pros and some cons. One con in the text says, "Imagine a computer thqat knows when you're happy or sad, For examples, if you smile when a Web ad appears on your screen, a similar ad might follow. But if you frown, the next ad will be different." That could be really upsetting considering how annoying some ads are. For example if you have a cat but it is showing an ad for bird food, what will that be useful for?
