Photos: Five of the best touchscreen mobiles

It may have passed everyone by but Palm has been doing touchscreen gadgets for donkey's years - aeons before the iPhone was even a twinkle in Steve Jobs' eye - so no touchscreen round-up would be complete without a nod to Palm.

It's still regularly refreshing its Treo range and keeping its options open with both Palm OS and Windows Mobile devices.

Pictured here is its latest offering - the Palm Treo Pro - which comes with a little bit of Bill Gates inside.

If you like to mix things up when it comes to input systems the smaller touchscreen and easy-access front-mounted full Qwerty keyboard take a 'best of both worlds' approach which has long been popular with senior execs.

Verdict: Enterprise class
