Initial Analysis - The Discrepancy appears to be - why is it that computers built after 2003 is only 40% of the returns - not 50% of the returns - Or rather - why do computers built before 2003 60% in returns ?
A. All computers, whether they were built before or after 2003, were scrutinized for their performance during the replacement.
REJECTED - Performance scrutiny does not explain why 2003 computers were lower in numbers.
B. The average life of the latest computers is estimated to be 11 years.
REJECTED - If this were the case, we should have had more computers built in 2003 coming in.
C. Advent of a new technology in 2003 made the computers a lot more robust and durable.
RIGHT ANSWER - This explains the reason why computers built from 2003 are still in use - and consumers are not seeing a need ot replace these with new ones.
D. The computers built since 2003 had more processing power and ran more sophisticated softwares.
REJECTED - THen the returns should have been lower than 40%, not nearly comparable to the computers built before 2003. (60% is approximately comparable to 40%, considering the timelines)
E. Zen Computers would have benefited a lot from this scheme if it had rolled it out two years earlier when even computers before 2003 were still in use.
REJECTED - If this were true then we would have seen more pre-2003 computers than post 2--3 computers. REJECTED.
