Re: 12.04 Vs 13.04
I think the phrase "Your milage may vary" is very apt.
Also, I love it how people use the word "commercial" to describe Ubuntu, and think it's an extreme insult or something. Ubuntu is a commercial distribution. Always has been, and Canonical has said so since the beginning. Incidentally, that's why Ubuntu is hosted at a ".com" web address. Every moneymaking feature in Ubuntu (Ubuntu One, Music Store, Ubuntu Software Center, Shopping Lens) has been greeted with shock by a small segment of Ubuntu users who have always assumed that Ubuntu is some sort of non-profit community-led distro.
I try to treat the cause, not the symptom. I avoid the terminal in instructions, unless it's easier or necessary. My instructions will work within the Ubuntu system, instead of breaking or subverting it. Those are the three guarantees to the helpee.
