We road tested the futuristic Azentek SmartMirror and got the feeling that it could be the next big GPS must-have or the next big safety hazard.

You’re driving past a fast food chain or roadsign, and suddenly an electronic image of a coupon appears in the corner of your windscreen advertising “$2.00 off any Burger Meal”.

The n35 is a complete navigation kit comprising a capable PDA with integrated GPS receiver (that folds down flush into the back), CoPilot Live 5 software, a sturdy windscreen mount and a cigarette lighter adaptor. At this price, it’s noticeably the cheapest PDA on test.

Impressive and free antivirus and antispyware package

Heartily recommended, but not a massive leap forward from the previous version

Almost on a par with the best value sat-nav – TomTom’s ONE – and with features that might make it more attractive to you

Expensive, but the features are packed in. Just note the lack of Wi-Fi and some strong iPaq competition.

Look ma -- no hands! Looking cool, but does Jabra's BlueTooth hand free phone speaker enhance your life?

Laser weaponry looks like becoming part of future army's arsenal, including non-lethal "flashes" designed to stop car drivers.

Not everyone is sold on Windows Mobile Professional, but if you're a fan, then Samsung's latest QWERTY phone is worth a look. We size up the Samsung i780 with Blackberry's Bold to see how they fair.

Still the easiest GPS to use, the new third generation TomTom trounces the competition.

Fantastic hardware. The GPS software is mediocre, but you can buy your own.
