The funny thing about contemporaries is that they are very diverse and one person's "got to have it" is another person's <yawn>. IMO many contemps can be trickier to photograph - as many have a lot of depth to them. I started collecting contemporaries after about a decade a collecting vintage (in addition to, not instead of). I found that moreso than vintage - it helps to actually to actually hold it in the hand to really appreciate the skill that went into making it.
The diversity of design and execution is so broad as to almost defy description and artists are constantly coming up with radical new design concepts. Some contemporaries require huge investments in time to prepare, craft and finish them. Ask a contemporary artist how much time goes into a specific piece and you will often be amazed.
Like vintage it is a "buy what you like" emphasis.
