Pros:
Appearance: Nice texture, attractive & straightforward
Max versatility WRT content arrangement
Continuity: Can fit more stuff on them than on short shelves
Not too complicated to DIY
Probably less expensive than buying a freestanding shelving unit of similar quality
Cons:
Dark wood might not look good where I need these
Commitment to location of shelves is required
Commitment to building project required; wood could sit around for months before commencement
This is kind of pretty, especially if you swap that flower thing out for something else, but it can't hold very much.
