Citing "sources close to Intel", TGDaily claims that Intel will be delaying their Montevina notebook platform until July 14th, with a full line of chipsets not shipping for "a couple of weeks later". The reasons for the delay are believed to include FCC certification holdups as well as integrated graphic chip failures.
