"Please explain to us how the 360 has such a high attach rate if console sales are significantly inflated. According to you each 360 owner should on average purchase 20 games."
You're creating a question that is completely irrelevant. I knew you wouldn't answer, so let me show you further proof.

Wanna dismiss this study too? This was done by one of the many companies who replace your system if it dies. The name of the company is Squaretrade. When they replace your system, Microsoft gets another sale. They purchase a new system, and send it to you. Not Microsoft, THEY purchase it.
"This analysis examines customer reported failure data on over 16,000 game consoles purchased by SquareTrade customers over the past two years.."
"Looking at the first 2 years of use, we found that Wii consoles had a reported failure rate of 2.7%, significantly lower than both the Xbox 360 and PS3 consoles. When including the infamous “Red Ring of Death” (RROD) problem that has plagued Xbox 360 systems, the Xbox 360 had a reported failure rate of 23.7%, nearly 9 times that of the Wii. PS3 consoles ranked in the middle of our study, with a reported failure rate of 10.0% over the course of 2 years."
"With nearly 1 in 4 systems experiencing a reported failure over 24 months, we found the Xbox 360 to be historically the least reliable of the 3 game systems."
"Microsoft’s policy may result in an underreporting of failures by Xbox 360 owners to SquareTrade, relative to the other two consoles. Because the RROD problem is so widely known to be covered by Microsoft’s warranty, we believe that more customers bypass SquareTrade and reported failures directly to the Microsoft. In a survey of SquareTrade customers with Xbox 360s conducted by email, SquareTrade found that over half of our customers who experienced a RROD error reported their problem directly to Microsoft without contacting SquareTrade."
"With that caveat in mind, applying the survey data to the analysis shows that the Xbox 360 failure rate could be as high as 35%."
So here, I'll answer your question, so that in order to reply, you will have to respond to mine. (Which you can't)
I show the 360 attach rate being 9%. If an independant study shows 54.2% failure rate, and a Squaretrade study shows 35%, with around 24% being replaced without going through the warranty, that would say ~24% (Rounded for ease) are inflated.
So if you take 9% attach rate, reduce the number of consoles by 24% which gives you (if you're being generous) a true number of 34.3M consoles out there, (This would be based off of Squaretrade numbers, which would NOT include those systems replaced by Microsoft, thus would NOT include ANY serviced by Microsoft 360's, just the percentage of those replaced by 3rd party insurance, and would not even include those serviced by Black Tie, Wal-Mart etc.) you end up with an attach rate of around 13%, rounding and being generous for the sake of argument.
I've now responded to your pointless question, let's see you answer mine. (You won't)
