You may like woodish bookcases, but I do not like. Without option to choose: wood, glass, metal, …, or just flat/clean it is ugly and crazy. Wood-simulated case on portable digital device: it is just stupid.
Why is realism stupid? If I flicked through a long list of what look like DVD titles on a retailer's website it wouldn't entice me to pick one. Seeing realistic-looking books on a realistic-looking bookshelf makes me think of picking an actual book up off an actual bookshelf, and thus the whole situation is more lifelike. It entices me to 'pick a book up' and read it, whereas the cold and unrealistic slew of DVD-style images that look like they're books up for sale on an online website does not entice me to read at all. The realism is non-existant and thus my interest is lost.
