1. Excessive models. They make this look work than it is by essentially having 2-4 customizations of the same model and presenting them as different models.
2. Confusing attempts to segment. Having the first step on the website be choosing which "segment" you want confuses the user. I'll pick a segment, then be unsure if I'm not seeing models that I'd like to see. Savvy consumers assume that "Home" mean "crummy," but "Business" isn't exactly right either.
