As an example of many bits of text around, take a look at this.

I'm not saying protien shakes are bad, but just that in general, whole foods tend to be a healthier choose for a number of reasons.
I love the idea of a quick post workout smash it in shake to get everything, but I have no idea what else is in that shake.
Pardon the pun but it's just food for thought. I will never be a calorie counter zomg must eat my specific protien meals through the day kind of guy, I like a post workout as I recover better and my loads are not heavy enough to really require ultra concentration on my nutrition, my choices are healthy enough that I'm in good enough shape without that level of scrutiny (but again my goals and loads are low).
