The Nokia 5140 is the big sister of the 5100 device, which was released a while ago by the Finnish giant. The handset had some minor flaws which weren't much to worry about, but they have been fixed in this model. The 5140 is also upgraded with a VGA digital still and video camera, Push-to-Talk service compatibility, superior data capabilities and some other minor enhancements.

Optus and Telstra networks currently support the Push-to-Talk service which is a big hit in the United States and is bound to be the next best thing for corporations in Australia due to the almost limitless connectivity range of the devices. I wasn't able to test the PTT service on the 5140 however – sorry!

The splash, shock, and dust resistant Xpress-On™ shells of the 5140 make the handset perfect for those in rough conditions that need a resistant companion with added benefits like a digital camera, torch, and compass.

The 5140 only had one major disappointment for me, which was the lack of Bluetooth. Having Bluetooth in a mobile phone aimed at a rural environment would almost be expected by the consumer, but hopefully Nokia will learn from this and incorporate it into their next handset!

The Nokia 5140 is available now for around $599.
