Though it's a pricey investment at $500 (with a two-year contract from Verizon Wireless; it's also available from Sprint), the Treo 700p works wonderfully for office duties. Working with the included Documents to Go software, I easily viewed and created Word, Excel, PowerPoint, and PDF files. Using these apps and navigating menus are much easier on the Palm Treo 700p than on the Windows Mobile-based Treo 700w. The Palm operating system streamlines the interface so you don't have to click multiple times to get results. The 700p's touch screen and keyboard contribute to the simplicity of opening apps and navigating pages.
The Treo also works well as a phone. My conversations sounded okay on both ends using either the handset or the speakerphone, though the speaker's sound was too high-pitched for my taste. (Luckily, I seldom need to use the speakerphone.) I do check my e-mail often, however, so I appreciate that Verizon's 700p (the version I tested) can wirelessly sync with my e-mail and calendar on my PC at the office or on the one at home--as long as the computer is turned on.
Because the Treo makes it easy for me to stay in touch, I don't need to tote my laptop everywhere. But if I do take it with me, I can use the 700p as a modem to get a Web connection, connecting the notebook via a cable or Bluetooth. To get this dial-up networking feature, you must subscribe to Verizon's BroadbandAccess Connect, for a $15 monthly fee ($30 if you don't subscribe to a voice plan). Verizon and Sprint offer EvDO, so users can expect broadband-like data connections.
Unfortunately, of the three devices I looked at, the Treo 700p is easily the most expensive--and that's before you factor in the service plan. The voice plan starts at $80 a month, and to that you have to add $15 a month if you want BroadbandAccess Connect; plus there's a $35 activation fee. If this price structure fits in your budget and you need an office workhorse, the 700p is your top choice. For more on the 700p, read Senior Associate Editor Melissa Perenson's review.
