iPhone 3G S vs Palm Pre: The Battle Begins

Not only does the Pre offer a modern, Web-oriented OS -- suitably named WebOS -- but its design leadership comes from Apple, including key players from the original iPod team. So there’s reason to believe that the Pre mixes the technical smarts and elegant usability that make the iPhone a tough device to beat.

If the battle between the BlackBerry Bold and the iPhone 3G was in essence a replay of PC versus Mac, the battle between the Pre and the iPhone 3G is more like a battle between Windows 7 and Mac OS X. The matchup, on paper, is close. So we set out to dig deeper. Galen has spent a lot of time with the iPhone as part of InfoWorld’s previous mobile deathmatch between the iPhone and BlackBerry, while Brandon bought a Pre as soon as it came out and has quickly made it a key part of his everyday life.

Deathmatch: E-mail, calendars, and contacts Galen: Until the iPhone 3.0 OS update became available last month, I would have rated the iPhone and Pre equal on e-mail, calendars, and contacts. Both can connect to Exchange, IMAP, and POP accounts; make and synchronize appointments; and manage contacts. Both allow for “push” synchronization with Exchange. Both preserve your Exchange folder hierarchy for mail and make navigating among folders a snap. And setup is easy.

But with iPhone OS 3.0, the playing field has changed. First, iPhone OS 3.0 allows iPhone and iPod Touch users to initiate calendar invites, which the Pre can’t do. And although you can search for e-mail in the Pre’s e-mail app (which the iPhone 2.0 OS could not do), iPhone 3.0 lets you search within your mail and across all applications -- the Pre can do neither.

Brandon: If you get a calendar invitation as an e-mail attachment on an iPhone, such as from a Notes user, you can't accept it from your e-mail; the iPhone can only sync invites already handled by Exchange. Plus, you can't move an event from one iPhone calendar to another, such as from your personal calendar to your work one. That's just dumb.
