David Meyer has just phoned in a hot news tip moments ago from a meeting he's been having with Acer. The vice-president for Europe, Massimo D'Angelo, was getting excited about AIO, the company's forthcoming All In One PC, with all sorts of things like multitouch, things to show off all the wonderful capabilities of Windows 7 - and said that it would be in-store at the back end of September, using Windows 7 technology. (see here for David's report on Windows 7 RC1).
David asked whether D'Angelo had just outed the release date for Windows 7. He replied no, the AIO would go on sale on the 23rd of October "and not a day before".
There was a flurry from the ranks at that point, and the marketing guy looked as if he'd pay almost anything to have Massimo retro-fitted with Control-Z. But what was said could not be unsaid - and while there's no confirmation of the date from anyone else, it is our firm impression from the circumstances of the blooper that it's accurate.
