At least they moved to H55/H57, which is a platform that should sell a lot, rather than the brain-damaged P55 platform, which most sites spend a lot of time trying to convince (not that successfully, based on the bad sales) is a great platform.
Lynnfield/P55 is such a strange product, and appeals to such a limited segment of the market. It's not cheap, but it's a high-end product either. So, you get squeezed by x58, which is the real platform, or LGA 775, and now H55/H57 from below. It's not a big market segment, and I think it makes Intel's line a little confusing to average consumers, especially since the Clarksdale CPUs overlap it in cost from below, and the Bloomfield do from above.
It's obvious Intel didn't want to release CPUs with an IMC for the mainstream until they could move the IGP on-board the CPU. Since the IGP has to use the memory controller, there are compromises however you do it when you have an IMC. You either go to the processor, or you add the logic on the IGP (making it redundant), so Intel avoided that problem by putting it on the processor. The P55 is again neither fish nor fowl. It's got limited PCIe lanes, but doesn't have an IGP either.
There's a small segment where it makes sense. It's power efficient and the performance is only slightly less than Bloomfield in many situations, but I think the average consumer is going to find the H55/H57 much better for their needs (an IGP is critical in this market), and the enthusiast will want the full-blown Bloomfield. For that reason I think these motherboards are significant even though the P55 isn't. Maybe you don't want it, but, you'll probably have a friends/family neighbors asking about a computer with these products. They aren't technical marvels with their weird memory controller placed in the video controller, but aside from the distasteful technical compromises Intel made, they still address the market and needs of most people very well. The only one that is so offensive I could never bring myself to recommending is the new Pentium version. It probably is fine for most people, but it's so offensive, it's painful to recommend. I think LGA 775 is better at that point. Or AMD, of course.
