iPad users spend three times longer playing games than on the iPhone, and developers also earn more per user from in-app advertising on Apple’s touchscreen tablet, according to a new study from Mobclix (http://www.mobclix.com), a mobile ad exchange network.

If you count the iPad as a notebook (and why shouldn’t you since many consider it a netbook replacement?), Apple is now the number three computer vendor for portables, passing Asus, Lenova, Toshiba and, yes, Dell.

Connecticut’s Attorney General Richard Blumenthal said Monday that e-book deals between Apple and Amazon and major book publishers may be anti-competitive, reports “MarketWatch” (http://macosg.me/2/mm).

Blumenthal’s office said he is investigating whether these agreements lead to less competition when it comes to book prices. “These agreements among publishers, Amazon and Apple appear to have already resulted in uniform prices for many of the most popular e-books — potentially depriving consumers of competitive prices,” he said.

Microsoft’s Macintosh Business Unit (http://www.microsoft.com/mac) will ship Office for Mac 2011 in late October. Reportedly, the prices will undercut the current version of the office application suite by 20% to 50%.

Microsoft Office 2011 will come in two editions: the Mac Home and Student version and a Mac Home and Business offering. The former includes the Word word-processing. The price will be US$119 for a single license and $149 for a family pack that allows for installs on three Macs.
