What claims to be unreleased footage of ‘Switch’ ad star Ellen Feiss proselytizing Apple’s PowerBook G4 has appeared.

The famously vague Feiss delivers her praise for the portable Mac, saying: “It’s really fast and it’s silver ...and I don’t have to watch airplane movies any more”.

She also considers: “I was wondering how my friends where doing their homework at home and I thought, hey, this is really great”.

Feiss is also famed for her appearance in one of Apple’s TV advertisements as part of its 'Switch' campaign.
