There's been plenty happening in technology to get our readers fired up this week. From the EU revealing its plans to investigate Apple over eBook pricing to the BBC rolling out its global iPlayer app to iPhones and iPod touches. Here's the most commented stories on PC Advisor over the last seven days.

EU to investigate Apple over eBook pricing

The EU revealed this week it will investigate Apple and five publishers over the price of eBooks. Hachette Livre, Penguin, Harper Collins, Simon & Schuster and Verlagsgruppe Georg von Holzbrinck are also being investigated by the European Commission, which is concerned the firms may have "engaged in anti-competitive practices" regarding the price of eBooks, "possibly with the help of Apple", which breaks EU antitrust regulations.
Maccyroo said: "This was always coming. It was just a matter of time."
"Before eBooks this exact same problem existed in the traditional paper book industry. Remember books used to be made of paper. WH Smith who also own Waterstones et al and the retail book industries battles over the ending of the 'fixed price agreements'," he added.
Meanwhile, Ian, Exeter urged the EU to also "investigate Apple for its anti competitive attitude to the Android invasion. Apple suing everyone in an effort to kill Android is not on".

BBC iPlayer app made available on iPhone and iPod Touch

This week, the BBC announced plans to roll out its global iPlayer app to Apple iPhones and iPod touches. The app for the catch-up service was initially made available for Apple iPads only in July this year and allowed users in 11 countries in Western Europe including France, Germany, Italy and Spain to watch BBC shows, such as Doctor Who, Top Gear and Eastenders as well as classic programmes including Fawlty Towers and Only Fools and Horses, on-demand rather than just catching-up on the shows broadcast over the last seven days.
Old Bert said: "Can't for the life of me make any sense out of this who would want to watch anything on a Phone?" while the bunker believes a significant portion of people who pay the licence fee do actually benefit from the alternative means of viewing including the iPlayer service.
"Things can be better for sure, but ultimately the BCC reflect the majority, but keep the door ajar into the future."

Two thirds of firms avoid flexible working technology

Two thirds of UK firms have not implemented flexible working technologies, such as cloud computing and video conferencing, because they believe it is too difficult to integrate into every-day practices, says LifeSize.
Furthermore, more than half (57 percent) feel it will not be easy to adopt these technologies within their business.
Hamzah Kattan said the fact 57 percent feel it will not be easy to adopt says it all.
"It's either a combination of ignorance and resistance to change or it underscores a lack in the market for professional flexible technology integration services."

Apple thinks Kindle Fire will push users to iOS, analyst says

Apple executives believe that the iPhone 3GS and Amazon's Kindle Fire will be two key devices that will expand the user base of iOS. That's according to JP Morgan analyst Mark Moskowitz, who met with Apple's chief executive Tim Cook and chief financial officer Peter Oppenheimer recently, reports Apple Insider.
Ian, Exeter said: "A few weeks ago I bought an Asus Transformer and that was a mistake, no way can it compare to an iPad2. That tablet alone would drive purchasers to buy an iPad2".
Maccyroo added: "If you had waited a few more months then you could of had the latest model of the Eee Transformer [due out early next year] which will be the first tablet with a quad core CPU. It will trounce the iPad2 for speed and usability/flexibility. It will be interesting to see what CPU and graphics hardware Apple uses in the new upcoming iPad 3."

Swiss researchers build silicon chip alternative

Swiss researchers have created the first computer chip made out of molybdenite (MoS2), a naturally occurring mineral that has been touted as a low-energy alternative to silicon. Molybdenite is being compared to graphene, another flexible semiconductor that many regard as the natural successor to silicon. IBM researchers rhave already created a graphene-based integrated circuit that is able to operate at frequencies of up to 10GHz.
However, Mr_Mistoffelees said: "8GHz plus has only been achieved using cooling solutions wholly impractical for everyday use".
