PC World is back in-stock with Advent's Vega tablet, though it's unclear how long availability of the in-demand Android slate will last. Having sold out on two occasions already, the £249 ($398) Tegra 2 tablet is showing as available for home delivery - but not in-store reservation - online.
Meanwhile an official case is also confirmed as on the way for the Vega, though we don't yet know if it's a basic sleeve or something more ambitious like the iPad's folio which props the tablet up for easier typing. More details on the Vega in our hands-on.
Update: Looks like all the stock has gone again.
