So far as I know, Intel isn't release the Core i7 architecture in notebook form for still a little while longer. So to me this sounds a little irresponsible.

The biggest problem in general with 3rd party chipsets has classically been the memory controller. This is because memory management within modern architectures has grown SO advantaced an complex that even when Intel is communicating the architecture internally, the chipset teams have difficulties getting it right. This is why Core i7 with integrated memory controllers is so important. It's also why 3rd party AMD chipsets don't fail too miserably.

I personally don't feel comfortable using a chipset designed outside of Intel for memory access.

I hope that this is a classic case of someone calling a dingy a yact. Maybe they'll continue to use Intel chipsets (at least until i7) and simply include an nVidia GPU.
