Although the article is a joke, I do feel a bit old-mannish about this sort of thing at times. Can't be bothered to learn the guitar? No problem, press some buttons along to a Chili Peppers backing track. Hey presto, you're making music! It's all just a high-tech version of Vib Ribbon to me anyway.
And why is it only music games that provoke this kind of navel-gazing "is it the same as the real thing" article? Nobody at the Grauniad is writing articles about how they should get a tryout for Man Utd because they're unbeatable on FIFA '09, are they? Although if* the papers are to be believed, at least our youngsters still find the time to go out and do some real stabbings and shootings when they're not caning Halo 3 or Grand Theft Auto IV.
In the interests of full disclosure I will admit that I have given in to the temptation of playing EA Skate instead of going out on my board when it's raining, and dark, and cold, and I'm just not feeling up to it. But if you try to play the guitar when you're tired or hungover you only hurt your neighbours - the chances of breaking a bone or disappearing under a bus are pretty low... :)
* giant-sized "if" that you can see from space goes here
