Today's Tech: Apple announces new Intel Haswell-equipped iMacs and China reportedly relaxing rules on Facebook and Twitter usage

Google has argued that its Books Library Project, for which the company has scanned millions of books and made them available online without authors' permission, does not violate copyright laws. Plaintiffs in the case - The Authors Guild along with photographer and graphic artist groups - are claiming that the project is a massive copyright infringement and are seeking damages and royalties. If Google loses the case, the company could be forced to pay over $3 billion (£1.9 billion) in damages and end the project, which has cost it around $40 million (£25 million) a year. However US Circuit Judge Denny Chin has suggested that he may be inclined to side with Google, by citing a number of examples in which the project has enabled people to get information, including his clerks.

Budget Chinese smartphone maker Xiaomi has announced the sale of 10 million units of its flagship smartphone, the Mi-2 and variants, the Mi-2S and Mi-2A, in 11 months. Considering Xiaomi only launched its first device in 2011, and it pretty much sells in China alone, the figures are rather impressive. The smartphone maker also only produces small batches of its devices at a time. When it released its cheapest ever offering, the Red Rice, last month, the initial 100,000 devices sold out in 90 seconds and gained seven million reservations. Highlighting the strength of the budget smartphone market in China, and adding to the mystery as to why Apple has not priced the 5C lower, Xiaomi recently pushed Apple into seventh place in the country.

Apple has announced a new range of iMacs that come with improved processors, clearer graphics, updated Wi-FI and faster flash storage options. The all-in-one desktops ship with Intel "Haswell" Core i5 and i7 processors depending on the model chosen with the familiar 21.5in and 27in screen sizes available across the range. This starts with the 21.5in iMac that has a 2.7GHz Intel Core i5 processor with graphics powered by a new Iris Pro chip. On the next level up there is a 21.5in and 27in model that both have faster 3.4GHz Intel Core i5 processors and NVIDIA GeForce 700 graphics that claim to offer performance that is 40 per cent faster than previous iMacs. For those that need even more performance there is the chance to upgrade to an Intel Core i7 processor offering up to 3.5GHz worth of speed.

China is set to relax its stringent rules on Internet usage by allowing Facebook, Twitter and a number of other restricted sites to be accessed in a planned free-trade zone [FTZ] in Shanghai. The South China Morning Post cites anonymous government sources as stating that sites deemed sensitive by the Chinese government will be allowed to operate in the zone. China will also invite foreign telecommunications companies to bid to provide Internet and certain services within the FTZ. The move is being made to make foreigners "feel like at home" in the FTZ, according to a government source quoted by the same publication. Chinese citizens haven't been able to access Facebook and Twitter since the government made the decision to block them in 2009 following claims they stoked riots in Xinjiang province.
