While having the most up-to-date software on your computer is usually an excellent idea, the LifeHacker article doesn't say anything about the reason why. Just that you should do this, because they say so. Call me a rebellious fool or whatever, but when I read such garbage, I am inclined to do just the opposite.
Then again, I don't use Chrome on my PC's...where 99.9% of my internet surfing takes place anyway. My systems are really a 'No Chrome'-zone. As I have Android with Google Play, Chrome comes with that like the unwanted stepchild and gets treated as such, because I am not allowed to remove it from my phone.
