That woman is worryingly unattractive. If you accept her as having an unfeminine aesthetic, and more a tomboy image, then don't put her in a skirt - it just doesn't suit her. Next, she claims to be an artist, but shows no artistic traits. Thirdly, video editing is all about the software as a previous poster said - Avid, Media100, Final Cut Pro, Premiere or Vegas. The Pro apps are Avid (PC or Mac), Media100 (Mac), Final Cut Pro (Mac). Premier is borderline (PC and Mac) useful for After Effects and Photoshop integration, etc, and I know a few people who enjoy using Vegas (PC). I was surprised by the 2MB RAM criticism, as I thought 4MB was standard, since that's what came with my MacBook Pro.
These ads are painful to watch - especially as I've seen the trouble people have when they get their laptops home and try and use 'em. That said, I'm not an exclusive Mac fan - I love Windows 98, and prefer PCs for typing, web design, and desktop publishing. I use Macs for music and video editing. There are also plenty of annoyances and oversights in Leopard, but....these adverts are painful to watch.
Still - the audience is unlikely to be pro video editors. It just has to give the gist that PCs offer better value for money (and as far as hardware alone goes, they do). But I wonder if the way they linger on the MacBook in particular during each of these adverts, and point out a really weak criticism, is gonna work against them? If I were Microsoft, Apple wouldn't be in my ads.
That said, if Apple weren't in them, we wouldn't all be watching them online, and talking about them. =P
