reginos:
People who are aware of F1 history shouldn't be surprised by Ferrari's slump. Between the 1979 title (Scheckter) and the Schumacher era, Ferrari accomplished very little in spite of having the best funded team and some of the best drivers of the time (Villeneuve, Arnoux Mario Andretti, Mansell, Prost) racing for them. The Italian team's main weakness has been bad organisation and in-fighting among management.
"Napoleon" aka Jean Todt, managed to eradicate this illness of internal quarrels for a period of time but it seems we've had a recurrence after a few years of immunity. Todt left his post as CEO at the end of 2007 and his legacy also won Ferrari their last title, Constructors 2008.
Even Dietrich Mateschitz, a drinks entrepreneur with no motorsport background managed to set up a top F1 in record time, whilst Ferrari rest on their laurels as a mythical team

"Form follows function"
Even though you are making some valid points, I think you are being overly harsh as a critic.
First of all, Ferrari enjoyed great success in the early '80s winning the Contructors Titles in 1982 and 1983. After that though, they had a dismal decade and a half, untill 1999 when they won the Title again. Infighting and a bad structure were parts of the problem. They also had to deal with some unfair competition though, as in the early 90's for example, Williams got their active suspension software for free by none other than British Aerospace and McLaren took theirs from McDonnell Douglas! Of course Ferrari could not compete against the know-how of aviation and airspace conglomerates! 
Then, the glory years came, where they absolutely demolished competition and re-wrote the record books! 
Nowadays they seem to be in the wilderness again.
Their current predicament can be explained though. Ferrari was traditionally an engine specialist. Since engine development is frozen, this advantage of theirs has been neutralised. Also, they were relying heavily on track testing. Testing is virtually banned now and that has set them back considerably in relation to other teams that were relying more on simulation technology.
The sad truth though is that Ferrari, after the departure of Rory Byrne and Paolo Martinelli, are not strong enough in the technical department. Nikolas Tompazis does not seem good enough to design a winning car and Pat Fry has never shown brilliance in his previous teams either. Combine this lack of prowess on the chassis side, with the frustrating ban on engine development and the lack of testing and you have a stambling horse instead of a prancing one. 
By the way Easy, Lotus is clearly ahead of Ferrari, which brings the Scuderia to the ignominy of being the 5th team. One has to go many years in the past to find Ferrari being 5th.
Frankly I don't even know when was the last time that had happend...
