There are multiple ways to dial calls on the E65. There is the slide-out dialpad of course, but unlike most clamshell or flip phones the E65's 15-button navigation array works when the dialpad is not extended. A dedicated button on the handset's side puts it in listen mode for voice recognition dialing and commands. A long press on a Bluetooth headset's call button will do the same thing.

As in the E61i, Voice Aid lets you drive the device "blind," that is, without using the display or keypad. A very clear synthesized voice walks you through your contacts, call log, voicemail, and clock and enables very easy dialing of arbitrary phone numbers. It's easy, safe to use while driving, operable without breaking your stride while walking, and works in those environments that confuse voice recognition.

A text-to-speech facility, with a selection of synthesized voices that well exceed the quality and modulation range of software voices on Windows and Mac OS, is built into the E61i and E65. There is a message reader among the office tools, but the speech capabilities are really there for custom software to tap.

The fact that the E65's pricing and feature set are identical to the E61i's makes it clear that Nokia expects multi-unit E61i deployments to include less cumbersome, less flashy E65 handsets for managers and executives that need a phone most of all, but who also need to be fully plugged into enterprise solutions built around other Nokia E-series handsets.

If you have a bias against Windows Mobile, as I find a surprising number of people do, T-Mobile's Wing (HTC Herald) has the power to bring you around. It is a full-fledged enterprise handset, not an underpowered smartphone, that is in a league of its own with regard to style and usability. Wing leverages the extremely impressive Windows Mobile 6 to lend it high configurability, a large array of standard applications, access to a huge library of available applications, and flexibility in custom application development using familiar Windows tools.

What lands Wing in the mobile executive category is its tasteful looks and compact shape. Its case is completely covered in a soft-touch, scratch- and fingerprint-resistant, quietly iridescent midnight blue matte finish. Its only chrome flash consists of a thin ring around the circular navigation control and its center select button. The shape and finish were clearly chosen to skew neither male nor female.

T-Mobile's Wing has a right-sized touchscreen display that operates in portrait or landscape mode, and a circular navigation pad flanked by six convenience keys that wrap around the sides of the case. The USB/headset jack is covered by a rubber door that lifts and swivels out of the way. The Micro SD memory expansion slot is externally accessible and covered by a rubber flap that fits snugly when closed. Having all of its external openings covered lends to Wing's uncanny ability to disappear when it's not lit.

Wing is not a fast Windows Mobile 6 phone, but keep in mind that even at its best, Windows Mobile is, in general, not a performance platform. It is built for portability and guaranteed application compatibility across hardware vendors. To build Wing light and compact, its manufacturer, HTC, dialed back the device's clock speed and went with an application processor that lacks ATI's accelerated graphics (which other HTC devices use only in media player apps). Wing exhibits launch-time delays for many applications, but these can be reduced by disabling HTC's memory-sparing feature that removes programs from fast RAM once they are closed. Most Windows Mobile devices keep apps in RAM.

Unlike AT&T's 8525 (HTC Hermes), T-Mobile's Wing shipped as a Windows Mobile 6 Professional device (AT&T plans a free upgrade for 8525 users that was not available in time for this review). The differences between WM5 and WM6 are substantial, and mark a departure from the staid Pocket PC. Office is now a standard feature, so you can view PowerPoint decks and view and edit Word and Excel documents. The WM6 e-mail client is second only to BlackBerry, which is no small feat considering that WM6 does on the handset much of what BlackBerry shifts to the server. WM6 has HTML e-mail, an Outlook-like interface and even Outlook-like functionality, and Internet sharing (tethering) that is much easier to enable than it was in WM5. Further, Pocket Internet Explorer is much closer to a desktop model than it was in WM5. If you've got Exchange Server or a mail server compatible with it, WM6 takes on the attributes of a Windows desktop client. If you don't have Exchange, or if fate causes you to temporarily lose access to your IT services, WM6's Windows Live integration with its free Hotmail and Microsoft Messenger IM can be a lifeline. As small as it is, Wing takes full advantage of WM6 Professional.
