From the article:
The phone is built like a brick, and dead easy to use. I’d argue that unlocking it and opening an app (yes, it runs apps using a mix of Symbian and UIQ) is even faster and easier than on the iPhone. Example: To unlock it, you flip the side scroll wheel toward you with your thumb (it has five directions — roll up and down, flip back and forward and click inward) and them click it in. You’re unlocked. Locking is done the same way.
Once unlocked you scroll the wheel to pick from any of the five (user-configurable) apps on the screen. If you open the keypad flip to go fullscreen, the wheel scrolls down the full list of apps. Click the wheel to open. Congratulations: you just fired up an app with a few twitches of one thumb....
Finally, texting. You can tap out texts old-style on the numerical keypad, or use the (long-lost) stylus to peck at a fairly decent on-screen keyboard. Or you can use your finger and handwriting recognition to write them.
Maybe it’s just suited to my handwriting, but the accuracy of this recognition is close to 100%....
Oh, and did I mention the battery life — even after ten years — is still almost a week?
Good stuff. Charlie also mentions a few of the decade-old negatives, but kudos to him for sticking with a chunky slice of Symbian classique...
