I am extremely skeptical that a lawsuit that few people are even aware of will have any effect on either company's brand image. A lot of Apple's products could be called "iconic" - people with little interest in technology differentiate between an iPhone 3GS and an iPhone 4. I'd be surprised if anyone could tell a Samsung from an HTC. A lawsuit isn't going to change that.
I agree that most people haven't heard much about the lawsuit, but saying "I'd be surprised if anyone could tell a Samsung from an HTC" surely only applies to your acquaintaces.
Here in Uruguay they definitely will - and it is Samsung phones which sell the most, by far (we're very price sensitive which is a nicer word for poor :P ).
Totally anecdotal (but then again, so's the post we're all talking about here), but from talking to various non-technical people around the office a lot of people seem to think Samsung 'had it coming'. And let's not forget the jury found Samsung guilty, a jury that supposedly represents the common person.
So while we're all aghast at what's going on here it could be quite likely that a lot of people have sympathy with Apple...rightly or wrongly.
