Predictably with Windows 7 almost out (22nd Oct), Acer have a few more models of the Revo in retailers lists: “Acer Revo 3601 Atom 330 Dual Core 4gb 500gb Windows 7 Premium” for £302 inc VAT from Ballicom UK, for example.
Sadly, none of the Dual-core Linux ones have actually started shipping in the UK yet; it’s been weeks now since they were announced!
