Perhaps there's merit to the notion that all content should be free, but this item's nothing to do with that, it's simply a quick note recognising that Apple's iPhone has been the most succesful consumer electronics launch ever.

Eagle-eyed readers may recall the heady days of July when I reported a prediction the iPhone would be the most succesful product introduction of the 21st century.

Naturally, critics dismissed the notion as hyperbole, so it's nice to be able to report some supporting data from Research and Markets.

Those researchers today said: "By our calculation, the iPhone launch was the largest and most successful consumer electronics introduction ever done, exceeding other notable events such as the launch of the Sony BetaMax video recorder, Microsoft's Windows 95, and the XBox 360."

Another report today also suggest just how important to Apple - and the mobile industry - the product introduction has been. iSuppli today observed that the iPhone was July's biggest-sellling smartphone in the US.

From a standing start, the iPhone accounted for 1.8 per cent of all mobile handset sales to US consumers in July.

Apparently one quarter of iPhone users switched network to AT&T in order to get hold of the device. This is good news for whichever network does eventually secure rights to distribute the iPhone in the UK.

And pretty poor news for other mobile firms, I suspect.
