The iPod touch is more important to Apple than many people may think, claims analytics group Flurry. The firm says it tracks four platforms, and roughly 3,000 applications and 45 million people; within this, the Touch is said to account for 35 percent of user sessions. Of the over 58 million devices with iPhone firmware sold worldwide, the Touch is estimated to represent a little over 40 percent, or at least 24 million.
