On Tech Weekly this week: Aleks Krotoski speaks to Shannon Spanhake about the personal pollution monitor that she has created. The gadget could be fitted into a mobile phone, and could mean taking readings of air quality could be much cheaper and the data become much more comprehensive. But is anyone interested, and what are the implications? Could this affect your health insurance if you can be traced and identified as living in a heavily polluted area?
Aleks is joined in the studio by Bobbie Johnson and Charles Arthur, and on the line from Barcelona by Richard Wray. Richard is at Mobile World Congress where the world's phone companies are launching their new handsets for 2009. Richard tells us all about a new universal charger, Microsoft's new version of Windows for mobiles, and why Apple is the elephant that is NOT in the room. He also has wise words for anyone in Barcelona at present.
There's a look at your comments from the blogs and our Twitter feed, plus this week's other news, including the value of social networks, after an estimate that ITV's Friends Reunited could be worth as little as £20m.
