As for size, I'm not sure I am a fan of the tall, thin profile of this phone. It is 15mm thick and 50mm wide, which is perfectly OK, but with the slide down it is a lanky 109mm tall, and with the slide up it grows to about 140mm. Quite simply, that is a lot of phone for the average pocket, though its 119g is no bother.
Nor am I too happy about the general handling. Motorola has gone for flat buttons on the front fascia and they are small and fiddly to get to grips with. Those with fat fingers might find them a challenge. Inside the slide the numberpad keys are almost flush to their surroundings and I found them unresponsive to use at speed.
This is a quad-band GSM mobile with HSDPA. There is a front-facing camera for two-way video calling. Apart from its bendiness the Z10 has two other key characteristics. First, let's mention the operating system. This handset is built on UIQ.
This is the operating system we most usually associate with Sony Ericsson touchscreened smartphones, but here there is no touchscreen. Most likely you won't notice that the operating system is out of the ordinary, but those who are interested in such matters might be happy to see UIQ take beyond the Sony Ericsson implementation.
It is unfortunate, though, that during testing I found the OS to run slow at times. It often left me waiting for something to happen after a keypress, which in everyday use gets a bit irritating especially when you press again thinking the first press wasn't registered, then have to backtrack.
The other key characteristic relates to Motorola's tagline for this handset - ‘We're all film makers now'. You can use this mobile to shoot video, edit it on the phone then upload to the Web. The camera can mange up to 30 frames a second, and video length is limited only by the size of your storage space. Nicely future-proofed, the Z10 can cope with up to 32GB of microSD memory.
Video editing amounts to being able to do things like cut segments from a video and splice them together in new ways; use transition effects; add audio if you don't like the audio that was captured at the time; and add texts for start and end titles.
It is all a bit of a fiddle, but if you are prepared to work with it you can then use the built in copy of ShoZu to upload videos (and photos), to the Web.
