Do SmartPhones need Word, Excel, and etc file readers?

I wondered why Quickoffice was bundled with the Sony Ericson SmartPhone. I figured that if one can’t really type on a SmartPhone why is it necessary to read Word and other attachments on it. Well – I was wrong.
Mike Compeau, Business Development Manager, Mobility Electronics, provides this insight:
1. Why include a product like this on a smartphone?
The Sony Ericsson P900 is perhaps one of the most sophisticated smartphones available. Though it does not itself include an integrated keyboard like the Treo 600 smartphone competitor, the P900 does provide for very usable text input using the stylus. In this respect, it is very similar to the ~30 million PDAs which have been sold. The P900’s design target market is clearly business users, for whom access to e-mail is a fundamental requirement. In todays mobile business world, the most vital content of many e-mails is the various Word and Excel files attached to those messages, and the speed of business makes it more than just desirable to provide direct access to those attachment files–it is a necessity. Being able to open a file attachment and view it on a remote mobile handset is becoming obligatory in today’s market–the Quickoffice Premier for UIQ suite also allows business users to make appropriate changes to these documents and then forward them on to colleagues to assure that business decisions and processes can keep moving forward irrespective of the location of the decision-maker. It is our clear belief that ‘someday all smartphones will need an office suite’, and the reception to our recent Symbian OS/UIQ release of Quickoffice has indicated that a great many customers of these devices agree.
Wouldn’t this be more suited for a PDA where a keyboard is attached?
Equally suited, yes, but not necessarily moreso. Many PDAs, being ‘unconnected’ to the Internet, are used primarily for managing addresses and calendar events. Wireless smartphones, by contrast are used primarily for two things: voice calls, and email. The inclusion of Quickoffice Premier for Office file management, access, and editing could be seen as even more vital by the users of this specific segment of the handset market, than by the broader field of users of generic ‘PDAs’. Certainly, we have built a strong foundational business providing Quickoffice to PDA users on the Palm OS platform, but the percentage of all device users who use their handheld to view or edit Word or Excel files is much smaller in the PDA segement, than the percentage of true ‘smartphone’ users who rely their smartphone to keep in touch with e-mail messages, and therefore yearn for access to their attachments as well.
