Ion-based cat is out of the bag, Acer's Aspire Revo has reared its pretty head on UK retailer Play.com's website. While all four packages sport the 1.6GHz Intel Atom N230, from what we can tell there's two distinct hardware configurations here. The base price is £180 (US $267), and with that you'll get 1GB RAM, 8GB SSD, and Linux. The £300 model boasts 2GB RAM, 160GB HDD, and Windows Vista Home Premium. Tack on £50 more for a 3D controller and ten games, and for £330 ($440) you can have the full package along with a wireless keyboard / mouse. The listed release date is May 18th for all of them, and with any luck Acer'll go with that date and bring the nettop stateside sometime around then.
