Something of this nature you likely want to do "right" the first time around. It's definitely not something you want to get and then think "I should have waited". I'd probably be more gung ho, except that I have a 24" already, so I've fed the beast and I have enough to make sure that the 30 is the right one.
But you are right, in any tech item, if some people don't leap, the product can die early on. In this case with Benq, Samsung, and HP coming with 30" models. While the market isn't huge, given the cost, there is a recognition that the market is there. And it can support more than 1-2 vendors. The HP would be superb save that I prefer a brighter value than the 300 it is going to be capable of. It hits every other nail right though so if they improve the brightness I might go there. We'll see.
