Powered by a CO2 cartridge that can pretty much reach anywhere in the arena depending on how much pressure you allow to buildup between launches (members of the squad told me they're not allowed to aim for the lights), it's basically a surface-to-air missile.
One of the commanders of the British intervention force told me in 2000 his project was "to build the country back up, starting with the government army as the first building block".
For a handset that you expect to last two years, the rear cover feels cheap and tacky, and did not fill me with confidence about the build quality of the Z10 and how it will stand up to regular use.
