Archos has been using dual-core chips since 2002.
156mm wide is quite funny, that's like more than 3cm wider then the Archos 605 WiFi.
Anyways, it's the right thing by Aigo to start using Texas Instruments in their PMPs, but most probably the 720p playback isn't any better then other current generation DaVinci based devices, thus not working for 720p WMV, 720p H264 but only partly working for 720p Mpeg4 simple profile.
Looking at that, it seems this product has a module port and that WiFi is not a built-in feature. No mention of touch-screen eigther so I don't know what they are going to use the WiFi for.
