Photos: HP shows off latest laptops

The xb3000 notebook expansion base is meant to elevate a notebook display to a comfortable viewing level.

The xb3000 has a cable dock connector that links notebooks to power, home networks and peripherals, and it supports 10/100 Ethernet connectivity. The base also comes with integrated Altec Lansing speakers, and some models will bundle a wireless keyboard and mouse. The xb3000 starts at $249 (£133) and should be available in the autumn.
