Are a device's looks important? Yes, and to some more than others, but in this case we're talking a rather pricey speaker. There should be much more focus on sound quality.
The "looks" issue goes further though as it has become almost the primary concern by the "blog" reviewers out there for tablets, laptops, phones, eReaders, TVs, etc. I'd much prefer if the reviews didn't come out the day of release and were written by people that took the time to learn and use the devices. Kind of like Consumer Reports, but by people that understand and utilize technology.
