Today's Tech: Microsoft announces new Surface tablet range as Gmail is hit by major disruption

Microsoft has unveiled its new line of tablets with the Surface 2 and Surface Pro 2 launched at an event in New York City with the latter promising 60 per cent longer battery life. The new slates, which will go on sale later this month, represent to company’s second excursion into the tablet market and the Redmond-based firm promised the two have vastly improved performance compared to the previous range.

As some on Twitter have commented, it's the equivalent of a 'snow day' for adults. Google's Gmail service has been hit by technical disruptions, effectively curtailing work and personal activity for millions of people worldwide. The problems first emerged on Monday afternoon (23 September), when users reported problems sending and receiving emails from their Gmail account. Tests here at ITProPortal HQ have verified the grumbles voiced on social media and beyond, with delays and indefinite failures plaguing communications. It is not a complete outage however, with some user accounts appearing to function as normal, while others have been foiled in both sending and receiving mail altogether.

Tesco has today officially launched its tablet offering under the brand name Hudl. The device features a 7in 1440 x 900 HD screen, a 1.5GHz quad-core processor and 16GB of memory which can be extended to 48GB. The tablet runs on Android Jellybean 4.2.2 and is Wi-Fi - but not mobile data - enabled. It will be available to buy in around 1000 Tesco stores and online from 30 September at a price of £119. The cost is slightly higher than predicted by analysts, although there are cost cutting deals available for Clubcard holders which can bring the price down to under £100.

Just three days after the iPhone 5S and 5C went on sale, Apple has announced the sale of a record breaking nine million devices. Additionally, over 200 million iPhones and iPads across the world are now running iOS 7 following its release last week, making it the fastest software upgrade in history. "This is our best iPhone launch yet―more than nine million new iPhones sold―a new record for first weekend sales," said Tim Cook, Apple's CEO. The launch has not gone completely smoothly however, with many UK carriers frustrated and concerned by the lack of 5S devices being made available by Apple. Conversely 5C supplies have been plentiful.
