Many electronic devices produce sound, whether it's an MP3 player, a mobile phone, a PC or a game computer; in many cases, sound is an added value. The quality however does vary at times. DRD offers the solution by launching the R1 mini theatre audio enhancer. This compact gadget can be connected to the 3.5mm connection of any device and serves to optimize the sound quality. We received the DRD R1 from the Dutch distributor Digitrading, and tested it with several pieces of video/audio equipment.

Sony has launched a large version of it's famous Memory Stick PRO-HG Duo HX, crowning the range with a massive 32GB Memory Stick model. Sony Memory Stick HX already delivers impressive speed, so the introduction of a 32GB Memory stick makes it the perfect choice for handling the very large video files created when filming in High Definition video. The huge amount of memory space on the stick is also ideal for digital photography, whether you are using a sophisticated Digital SLR like the Sony Alpha DSLR, or a compact Sony Cybershot camera. The Sony Memory Stick PRO-HG Duo HX range also includes 4GB, 8GB and 16GB Memory Sticks.

The operating system often proves vital to your opinion on the user-friendliness of the phone, and also reveals a lot about its speed and applicability. Until recently, Windows Mobile or Symbian was generally used for the corporate market, but these days, this selection has been expanded by the arrival of the Apple and Google Android operating system. Unfortunately, I was not able to personally test the HTC G1, but my first impression of the Google Android operating system on the HTC Magic is very positive indeed.
