Apple just had a Q2 2007 Financials conference call and mentioned Apple TV and a subscription model–but for free software updates not for content–would be implemented. From what I gathered, iPhone and Apple TV will use subscription-type accounting to provide free upgrades that will “surprise and delight” customers. If anyone has further details about what this “Apple TV Subscription Model” refers to, please feel free to elucidate in the comments or drop me an e-mail.

By the way, Apple declined to announce the number of Apple TV unit sales to date.
