It is no doubt that the office use applications which includes Word, Excel and PowerPoint are the most popular applications among companies and schools in the whole world.They were first released in 1990, generated nearly a third of Microsoft’s revenue during its last fiscal year — about $26 billion of $87 billion in total.

However,the world’s largest software company, said on last Thursday that it would give away a comprehensive mobile edition of Office,and it will charge for nothing.

Nowadays,more and more people have began use mobile devices such as tablet and cellphone via the internet rather than a PC.Analysis show that not everyone needs a PC,they can do most of writing jobs on their mobile devices.Besides,Apple also canceled its paid office apps(Pages,Keynotes,Numbers)to free from 2014. Which makes people stared choose apps form Apple and other office apps like Evernote.These apps both can satisfy people’s needs,so they’d rather abandon Microsoft Office(because it’s paid).

Satya Nadella,the new CEO of Microsoft,who has pushed cloud and mobile computing as lodestars for the company’s future.Since Microsoft bought Nokia,it’s obviously Microsoft wants to make mobile become its new money machine.So it is important to attract people using their office apps.Microsoft’s new phone cancels the name of “Nokia”,it starts to use”Lumia”to name its phones.This will leave consumers a deep impression of the phone,and in the meanwhile,hence the brand value.People use other system like IOS or Android may find the free Microsoft Office apps are useful then they may consider buying a Lumia directly next time they change their phones.
