So in many ways it's buying it because I like the results, not because the client wants it.
I think this sums it up perfectly. At the end of the day, we're all tech heads and it's not easy to avoid being seduced by new, great looking imagery. For the vast majority of our clients, we distribute online or to DVD, so even our HPX300 is borderline over-kill. It's poor business to buy outside of what your clients want, in my humble opinion.
