Gear acquisition syndrome. That is what the topic stand for and it is a trap most creative people usually fall into. The idea of a new shiny toy will fix all of your creative problems.
Sometime it does, but mostly it is just wishful thinking and procrastination, to obscure the real issue.
Lately I have been really trying to think twice before making a purchase. Will this new piece of gear really do any good in my actual work flow or do I just like the idea of it?
