From a consumer perspective, Harman color products are a joke. We currently have two significant suppliers of colour film in the marketplace, Kodak and Fuji. They both make quality products. The only problem is the price. The only reason for a consumer to consider a new supplier, is if that supplier can offer a significantly lower price, at the same quality, or better. That's the power of competition.
There is absolutely no indication that Harman will be able to make a quality product any time soon, and certainly not at a competitive price. So, from the consumer perspective, the case is closed.
You could also look at this from an investor's perspective. If you buy some Phoenix, or Red, you've essentially decided to "invest" in Harman. Like any investment, it's akin to a lottery. You're hoping for potential future gains, with small initial outlay. It's stupid to be buying Phoenix or Red now, since there are absolutely no long term benefits to this type of investment. You'd be better off investing in shares of Harman, and hoping they can eventually come up with a competitive product, that will increase their share value. When you say "Haman should be given a break since they're starting from scratch in color film development", you're speaking from an investor's perspective. The free market doesn't care, and that's the consumer.
