National consumer inflation figures are worked out by the Office for National Statistics (ONS), which has a 650-strong “basket of goods and services” to calculate the Retail Prices Index.

Every year this typical basket is updated with old-fashioned things cruelly thrown out and new-fangled goods proudly displayed to reflect public spending habits.

This year sees the arrival of portable digital storage devices, which includes digital camera cards and Flash memory sticks, as well as MP3 players such as Apple’s iPod nano. These have dropped so much in price in recent years that had they been included a few years ago, inflation would be at an all-time low.

Joining flash memory are fruit smoothies, muffins and classic (non-chart) CDs.

Out forever go frozen vegetarian ready meals, CD singles, "stubbie" lager cans and 35mm cameras. Apart from veggie meals I'm surprised that little cans of lager and film cameras survived so long - can you still buy them anywhere?

The removal of Top 40 singles from the basket reflects the fact consumers are downloading music more, said the ONS. And digital cameras have delivered another mortal blow to 35mm film winders.
