In addition to the softmenu, Call and End buttons there is a Clear key and one that starts the built-in music software - I'll get to that in more detail later. These keys, and the number keys that are inside the slide, are backlit blue when activated.
The numberpad keys are flat and again separated by flush bars, this time coloured black like the numberpad keys themselves. They are easy to use at a fair old lick of speed.
Side keys are minimal with just a volume rocker and camera key sitting one on the left and one on the right edge. This minimalism and a pretty solid plastic casing make the 830 seem like a workaday handset.
And indeed, that is pretty much what the 830 is. This is a 3G phone with a front camera for two-way video calling. It is tri-band GSM and has Bluetooth, but there are no higher end features like Wi-Fi, GPS and screen rotation, either manually or via an accelerometer.
If you are a music fan, the messages are mixed. There is just 25MB of built-in memory, and an easily accessed microSD card slot on the right edge for adding more. What really irks is the proprietary connector for the provided in-ear headset which is shared by mains power and PC connection.
Am I the only person in the UK whose ears are shaped so that these devils won't stay in place? Maybe, maybe not, but even those whose ears are perfect for in-ear buds might prefer their own headset to the average one provided. There is also no FM radio.
A potentially very big plus for those who possess the right kind of ears and are OK with the music quality, is that I got 14-and-a-half hours of music from a full battery charge. Recently, only my own rundown test of the BlackBerry Storm has produced longer, and as far as non-smartphones are concerned few approach that playback length.
In general use I managed three days without access to mains power, which is more than I'd expect from a more fully-featured phone if only because I'd thrash the features.
