I really didn't grok how 'noob-unfriendly' the SR4 character creation system was until I had to guide my wife through it. She's a fairly casual gamer but has played games like Ars Magica and GURPS in the past. She was new not only to the 4th edition chargen system but to the Shadowrun setting as a whole. She was having a very difficult time wrestling the chargen system to fulfill her character concept, a Face/Infiltration expert, and needed a great deal of my help to build an effective character. I've heard this problem referred to as "system mastery", i.e. that it takes experience and skill with a system to make an effective character in that system. I feel like SR4 suffers from a fairly serious case of system mastery. Anything that will help players unfamiliar with SR rules and setting make an effective character that fulfills their concept will be a boon.
Also, I'm sick of using my substantially annotated GM screen.
