The Samsung Giorgio Armani has the same touchscreen interface as both the LG Viewty and the Apple iPhone but it is almost half the size and width of the Viewty.
The Armani comes with photo-editing software, which lets users remove people or brighten colours, and although the 2.6in screen is smaller than the Viewty's we were impressed that we could see exactly what we were doing. We were also very impressed with the three-megapixel camera that takes clear and bright shots.
A mouse is more comfortable than a laptop trackpad but does depend on a flat surface. The Gyration Air Mouse avoids this with a clever combination of sensors so it can be used in mid-air.
It is very small and comes with a pouch. It may not take up too much space in a laptop bag but it is not that comfortable for larger hands. It won't replace a full-size mouse.
There is trigger button on the underside to engage the in-air mode. It takes a little getting used to but works better in practice.
The third addition to the iPhone range, the 3GS, is a small step forward for Apple compared with the first two handsets, in that it introduces several features that similar phones have had for years.There are two new products here: the iPhone OS 3.0 operating system update available to users of older iPhones through iTunes, and the new hardware. The software introduces the ability to cut and paste text and images from documents or web pages and to send photos by MMS. A landscape keyboard has also been included.More people now use phones to take photos and the 3GS has an improved 3-megapixel camera with auto-focus
Blackberries are familiar to everyone who works in an office but so far Research In Motion, the Canadian company that makes them, has failed to crack the home market.
The Storm is its latest attempt to do just that. It's a touch-screen phone which means that its chief competitor is, yes, the iPhone.
It's available exclusively on Vodafone so now all four major networks in the UK have their own large touch-screen device. Heading the pack are O2's iPhone and T-Mobile's G1 or Google phone.
Many Bluetooth headsets have the disadvantage of making you look a little silly.
The Invisio G5 is an attempt to address that by making the headset as small as possible.
It was easy to pair the device using the clear instructions in the manual. Call quality was fair – incoming sounds were fine, but outgoing sounds were muffled and sounded far away.
Solwise’s Homeplug adapters do away with both network cables and the hassle of setting up wireless networks, because they using your home's mains electrical wiring instead.
Each computer or device to be added to the network will usually require both a network connection and a mains power connection. Where most Homeplug adapters use up a mains socket for themselves, the Solwise Piggy units are fitted with a mains socket of their own.

The Aiptek PocketDV AHD Z500 Plus is a fine example of the miniaturising trend. It’s small enough to fit into a biggish pocket and light enough not to be noticed.
The T-Mobile G1, commonly known as the Google phone, is the first to use the search company's Android operating system.
It's being talked about as a potential rival to the iPhone, with a similar large touch-screen, mapping with GPS, music and video playback and downloadable applications.
In addition the G1 has a slide-out keyboard and a few other nifty touches, but it falls down in a couple of places too.

At £75, Guitar Hero 3 is easily the most expensive video game we’ve reviewed at Computeractive.
On the other hand, you get a lot for your money: inside the enormous box you’ll find a special guitar controller. This is wireless, roughly two-thirds as long as a proper guitar, and shaped like a Gibson Les Paul. It has five coloured buttons on the fretboard, a “strum bar” switch where the strings should be and a tremolo bar.

If it weren't apparent already that the Zoostorm Fizzbook was a notebook designed for children, it becomes clear as soon as you take it out of its packaging.
Wrapped around the notebook's case is a green leather surround which extends at the back to form a handle.
It has an 8.9in screen and an Intel Atom N270 processor. It comes with 1GB of memory, although there is only 4GB of permanent storage.

Microsoft’s Lifecam NX 3000 is designed for use with Windows Messenger and skinny notebooks – skinny because the webcam attaches to a screen no thicker than about 2cm.
It is a 1.3megapixel webcam that takes impressively clear still shots. The camera was easy to set up. Once installed the camera uses its own dashboard, which has three buttons for snapping photos and recording audio or video clips.

Most computers use a built in sound card to play music and sounds. A new soundcard can offer better sound quality and sometimes more connections for recording or transfering audio.
This video demonstrates how to fit an internal sound card into one of the white PCI slots found in most desktop computers.
The Ubuntu desktop looks quite different to Windows with bars at both the top and the bottom. Tim Smith from Computeractive explains where everything is from starting programs to changing settings
