Having had the chance to play with a relative's Archos Video Recorder early last year, I've kept an eye out for Archos news. The Video Recorder I played with was impressive despite the large size - the current 40GB model appears to be slightly smaller but still weighs in at 350g (12.5oz).
However, Archos' new product is in a different league. The 400 Gmini 400 weighs in at a mere 160g (5.6oz) and features a 20GB hard disk and 2.2" 220x176 pixel 262,000 colour screen. Interfaces include USB2.0 and a CompactFlash slot and it can play MP3, WMA and WAV audio and Mpeg4, Xvid and Divx video. It can also play Mophun games, either on the onboard screen or on a TV.
