Viewsonic seem fairly clear about the G10S products final specs and seeing as their are some very similar / branded variants on the market already, it is likely that this will be available very shortly.

We’re talking about an Android Open Source 2.2 (no Market, Gmail, Navigation etc.) buid on a  Tegra2 platform with some talk (!) of Honeycomb. Certainly the specs seem ok, the build quality is acceptable and, to me, it appeared fairly light for 10 inch device. 3G was mentioned too so this might be the main difference over the Advent Vega version that already sells in the UK. Once again, pricing is going to be the key differentiator in this busy 10″ Android Tablet space. We should get that in just a few weeks. We’ll also be keeping an eye on Honeycomb ports over Q2 because with the docking station and potential USB host capability this could turn into something completely different over time.
