To determine the approximate number of iOS users at the start of 2006, we need to use the percentage change data provided in the graph for iOS for the years 2004 and 2005.
From the graph "PERCENTAGE CHANGE IN USERS (YEARLY)":
* **For the year 2004 (change from start of 2004 to start of 2005):** The iOS line shows a **-0.5%** change.
* **For the year 2005 (change from start of 2005 to start of 2006):** The iOS line shows a **+0.1%** change.
Now, let's calculate the number of users step-by-step:
1. **Users at the start of 2004:** 595,000
2. **Users at the start of 2005:**
The change from 2004 to 2005 was -0.5%.
Number of users = $\(595,000 \times (1 - 0.005)\)$
Number of users = $\(595,000 \times 0.995\)$
Number of users = $\(592,025\)$
3. **Users at the start of 2006:**
The change from 2005 to 2006 was +0.1%.
Number of users = $\(592,025 \times (1 + 0.001)\)$
Number of users = $\(592,025 \times 1.001\)$
Number of users = $\(592,025 + 592.025\)$
Number of users = $\(592,617.025\)$
Rounding to the nearest thousand (since the options are in thousands and the question asks for approximate number in thousands), 592,617.025 is approximately 593,000.
Therefore, the approximate number of users of iOS at the start of 2006 was 593,000 (or 593 in thousands).
The final answer is $\(\boxed{\text{593}}\)$.
