The main form of connectivity is Wi-Fi (802.11b/g), and hooking up to a network is as simple as connecting with a laptop.

The T3's Stretch Display

Overall, the Tungsten T3 isn't that much smaller than the Zire 71, but it does feel nicely compact in the hand and its larger navigation button is easier to manipulate with just your thumb. However, the "wow factor" comes into full force when you slide down the bottom of the T3's case to reveal the full screen mode. And it gets even better. The standard "silkscreened" Graffiti input area (so-called because its icons and borders are printed onto the screen's glass) is now replaced by a digital version, which can be hidden to reveal an even larger screen. We found this useful when writing long notes in Memos and viewing an expanded daily calendar view. You don't actually need the Graffiti writing area to input data into notes or Calendar items. With the Full-Screen Writing preference turned on, you can write Graffiti characters anywhere on the screen (you'll even see an outline traced on the screen as you write). But the crowning display enhancement is the ability to rotate the screen to landscape view, which was especially handy when viewing downloaded movie trailers (using the included Kinoma video player). If you're left-handed, you can change the orientation in landscape view so that the status bar and Graffiti input area are more accessible to your own orientation.

The T3 includes the familiar suite of Palm applications (Calendar, Contacts, Memos, and Tasks) as well as a number of third-party software title (ranging from Acrobat Reader to RealOne Player for listening to digital audio). Calendar has been given an Outlook-friendly makeover, adding an Agenda view that consolidates all of today's appointments, tasks, and new e-mails. With full-screen mode on, Calendar's month view now displays smaller calendars for the previous and next months.

Bluetooth wireless functionality is built in, and the Tungsten T3 still includes the BlueBoard and BlueChat for sharing information with other Tungsten users. For Web communication, Palm includes VersaMail and WebBrowser Pro, both of which can be used along with a Bluetooth phone. Additionally, VersaMail can access a corporate e-mail account, including Microsoft Exchange and Lotus Domino servers.

Java has also now entered the Palm OS arena, expanding the application development opportunities. The T3 comes with a few sample applets (including a periodic table that would be handy at our local pub's trivia night), but we'll have to wait for more development before Java becomes a full Palm OS tool.

Our only complaint, design-wise, is the placement of the Voice Memo button, which as been placed toward the top of the left side of the case, below the on/off button on the top panel. When turning on the device, our left hand's thumb continually triggered the Voice Memo app when attempting to turn on the T3. Note that you can also turn the T3 on by pressing one of the application buttons surrounding the Navigator, or by sliding the bottom case open. Overall, the Tungsten T3 is a Palm powerhouse, blending its traditional information management strength with new multimedia and connectivity functionality (both wired and wireless). It's about as perfect a personal productivity agent for professional settings as it gets. --Agen G.N. Schmitz
