Another issue: The BlackBerry integrates with all three major e-mail platforms: Microsoft Exchange, IBM Lotus Notes, and Novell Groupwise, as well as the Internet-standard POP mail protocol (but not the standard IMAP protocol). The iPhone ties directly into only Exchange, in addition to supporting both POP and IMAP for basic e-mail support on a variety of e-mail platforms. That's because the BlackBerry was designed from the outset to connect to corporate e-mail accounts, whereas iPhone was aimed at the consumer and is now being adapted for business. (IBM has announced its intent to make a native Notes client for the iPhone, but it's not clear when that might ship. Novell has announced no plans.)
The BlackBerry's platform support is "a big issue for customers who want to access their enterprise e-mail," says Jan Dawson, an Ovum analyst. But he suspects this disadvantage will be transitory: "The iPhone's first step was [support for] Exchange, because it's the most used platform. I wouldn't be surprised if Apple added compatibility with Lotus and other e-mail platforms down the line."
Another advantage for BlackBerry users is that they can have multiple applications running simultaneously. A business user can talk on the phone, chat in two IM sessions, and chart a location on TeleNav via a button that scrolls through applications. By contrast, iPhone apps suspend or stop when you switch from one to the other, Yager notes. For example, e-mail downloading stops while you browse the Web. That's not a big deal for when you're making a call or writing an e-mail and need to quickly switch to a browser, your contacts, or Google Maps to look something else, then switch back to your call or e-mail. But it can be an issue for real-time apps such as chat, video, and streaming media.
Browser wars 2.0: Going mobile?
Given these challenges, Apple no doubt hopes the mobile turf war shifts to the browser. Nearly everyone drools over the iPhone's supercool browser. Even Yager envies the iPhone's ability to render gorgeous Web pages, soon to fly over a 3G network. "When Apple goes 3G, it'll just stomp BlackBerry for users looking for a portable Internet terminal," he says.
But just how important is Web browsing to business users?
Gartner's Dulaney sees a real opportunity for the iPhone to make inroads into businesses thanks to its rich browser. While many business users will continue to choose BlackBerry for its resilient messaging, a significant minority will probably be driven to the iPhone's browser.
Mobile browsing among business users won't just be about surfing ESPN for the latest sports scores. And it'll hardly be about Google either. "It'll be more 'reactive browsing' on handhelds," Dulaney says. "Let's say you get a message from your bank that your balance has fallen below [a certain amount]. You launch a browser, go to the bank site, and move money over. What you probably won't do is hunt around for things because, even with the iPhone, it's still going to be painful."
The mobile browser may become more important over time, as Web-based software applications such as Salesforce.com's CRM continue to ride the cloud computing wave. "A [mobile] Web browser that accesses that kind of information is important," Dawson says. "But browsing is still very much secondary to messaging for the corporate user."
Dulaney and Yager contend that the iPhone's Web browser won't be the ultimate game-changer. Neither believes that the mobile browser will be the interface for a business user's most critical applications. It's difficult to imagine, for instance, working with e-mail attachments such as Office docs, PDFs, WAV audio files, and others on a mobile screen, even though the iPhone supports most of these for viewing.
"The BlackBerry is not in trouble," Yager says. "It has its disadvantages, and the browser is chief among them ... but the world would have to change for business users to use the [mobile] browser as the primary means to access their applications and data."
