Two new applications Quickoffice and Documents To Go allows you to create and edit Microsoft Office documents on your iPhone or BlackBerry. So which more nice? in iPhone or Blackberry? This is review by Arik_Hesseldahl in businessweek:

Years ago, I had dreams of utopian work where I wanted, armed only with a PDA. I wish my Palm organizer and a word processor, which are in my pocket and, finally, I managed to sort. I was able to install a word processing program and attach a time in place of the keyboard, but there is no wireless connection.

Now that PDAs have transformed into smartphones, I not only thought to be connected to the Internet and to my office via BlackBerry or iPhone, but also to be able to create and edit a series of Microsoft Office documents. Users of smartphones running Microsoft Windows Mobile software have this capability for a long period, and finally it comes to other popular handhelds.

I’ve tested two applications: Quickoffice for iPhone (around $ 20) and Documents To Go Premium DataViz for BlackBerry (around $ 70). Both products free of having to open your laptop just to make minor changes to a document someone sends you work. The DataViz is offering a little more advanced, but which side you are, it is a welcome development.

E-mail on the iPhone Docs Are No Snap

Quickoffice is the first iPhone application that allows users to create and edit Word documents and Excel spreadsheets and PowerPoint will be available on an update later this year.

Files much like what you see on a Mac or a PC screen, but compressed to fit the smaller display. Rotate the screen horizontally and a larger keyboard appears, allowing relatively easy to type. In both Word and Excel, you can copy and paste something that was not possible before.

Curiously, however, you can not do that easily with documents that arrive by e-mail messages. The problem is on the side of Apple. The iPhone’s operating system does not allow files used by a program in this case, the e-mail to be used by all other programs such as Word. Apple (AAPL) said it would resolve to have multiple software processes running constantly in the background, which would take a toll on battery life.

It is clever, if imperfect workaround. If a colleague asks you to mark a document, he or she can transfer it to a folder on the Apple Web-based service called MobileMe, and you can retrieve it from the iPhone. Quickoffice could smooth this process by supporting other Web services like Google Docs, Google’s free Web-based word processing and spreadsheet.

Spreadsheets Stand Out on BlackBerry

In comparison with Quickoffice, Documents To Go on the BlackBerry (RIMM) feels more like a traditional office suite. If you have a new BlackBerry Curve or bold, you already have a basic version of the program. But Documents To Go Premium adds several important features.

With both versions, you can open and edit documents in Word, Excel, PowerPoint, and arriving by e-mail, even if the editing options are few PowerPoint. The Premium version can also create files in the three programs, and even check your spelling.

I particularly appreciated the spreadsheet in Documents To Go I often look at a worksheet that follows Apple’s quarterly and annual sales of more than 10 years. It’s great to be able to edit individual cells by accessing them with the BlackBerry trackball. You can not do the equivalent of Quickoffice again, but this functionality will be added in the next update.

So I’ve reached my pocket everywhere utopia? It is becoming more closely. In general, I found Documents To Go to be more fully formed Quickoffice, but both products are evolving. DataViz, for example, plans to Documents To Go for the iPhone this summer. As the competition heats up, these applications will only get better.
