Last month Juniper Research said the number of mobile phone users making payments for digital goods was expected to reach 2.5 billion worldwide by 2015, a 40% increase from this year's forecast of 1.8 billion.

It's now published a new study that looks at all mobile money transactions. The company says the total value of mobile payments for digital and physical goods, money transfers and NFC transactions will reach $670 billion by 2015.

Anonymous opinions about technology are all over the web... and they're not always pleasant. PC versus Mac. Apple versus Android. WiMAX vs LTE. Even a relatively light-hearted rant can be misinterpreted. Still, if some unknown voice is trying to irritate you, you just ignore them - right?

The International Commission on Non-Ionizing Radiation Protection Standing Committee on Epidemiology has just published a report after analysing all published studies that examined whether there is a link between mobile phone use and the main types of brain tumour.
