A custom ROM for the Advent Vega Tegra 2 tablet has been released, adding in Android Market support along with Car Home, Calendar, Contacts, Genie (News and Weather), Gmail, Maps with Street View, Market, Talk, Voice Search and YouTube. The handiwork of MoDaCo’s Paul O’Brien, there’s also an optional “performance pack” which promises to speed up the tablet.

PC World has said that they expect more Vega stock by the end of this week, though the tablet is still currently unavailable.
