Review: Nokia E73 Mode
Apps
Because the E73 uses S60, literally thousands of applications are available from third-party vendors, many for free. The E73 has built-in access to Nokia's Ovi Store, which is a decent starting place to find applications. It isn't as easy to browse as the iPhone App Store, the Android Market or BlackBerry App World, but it serves well enough. Probably the biggest improvement here is that T-Mobile is allowing users to purchase applications from the Nokia Ovi Store and charge them to their T-Mobile account. That's a major hurdle cleared for Nokia, which used to require credit cards for app purchases.
Bluetooth
The E73 communicated via Bluetooth with every device I tested. That included two different computers, two pairs of Bluetooth headsets, stereo headsets, and an external stereo speaker. All the pairings and connections were easily accomplished and managed. Passing files from the phone to a computer and back was easy. Sound quality via Bluetooth headsets — both standard and stereo — was stellar.
Clock
The home screen clock can be set to analog or digital. The analog clock can be a little tough to read from an arm's length, however. If you want to check the time quickly, the E73 is not going to help you out. With the display asleep, hitting any of the keys doesn't bring the screen to life. You have to unlock the keyboard first, which takes two steps. Alternately, you can press any key and wait for the unlock message to go away. It takes several seconds. After it goes away, you can get a look at the clock.
