Why is it I now look at photography equipment and WANT it...?

For years I would go ages without photographing anything... and now I'm thinking about tripods, big memory cards, digital photo frames and even...

A digital SLR camera...

Problem is I'm a real amateur so I figure my camera is good enough, I look at the pics I've taken and wonder why I need anything better but I don't really have much experience re cameras.
