On the left edge of the phone is more usefulness, this time in the shape of a clickable scroller wheel for whizzing up and down lists of programs and contacts. Not only this, but Asus has also added a small close button just next to it, meaning you can operate the phone one-handed much more easily than most other Windows Mobile based devices. The software it runs on is right up to date too with Windows Mobile 6 Professional installed out of the box and, to the usual line-up of software suspects, Asus has added a launcher app, a call filter, the afore-mentioned Voice Commander and Remote Presenter, which allows you to control presentations on your laptop via Bluetooth.
The P526's standout feature, however, is its SiRF Star III GPS receiver, which allows you to download and install a myriad of sat-nav software, from Wayfinder to TomTom. This works well, getting a satellite lock quickly and holding it well. As it stands, though, the P526 comes with no GPS software at all out of the box. I liked the 2.6in 240 x 320 screen too. It's bright and clear, though it can be difficult to read in very bright sunshine.
It's a shame that the rest of the specifications are not so impressive. The P526 is a quad band phone, which means you can use it pretty much anywhere your travels take you. It has GPRS and EDGE, and Bluetooth as any self-respecting business phone like this should have, plus infrared. However, faster Internet speeds on the move are beyond it as there's no 3G or Wi-Fi for hotspot connection.
