I've been searching for a windows laptop which can make use of ECC memories, but this seems to be going nowhere. The original plan if msft to require ecc for vista seems far away. Are there no ecc memory based laptops?

Unless you are performing some specialty applications that require extreme reliability (engineering, medical etc.), regular Non-ECC will be fine. In my entire life, I have never encountered any memory problems due to not having ECC on my computers and I have had a lot, I mean a lot as in 11 home computers (yeah I'm crazy) and have repaired many many more. Usually, problems are due to either software problems or hard drive failures. Other problems are quite rare (but yes, they do happen to some).
Without ECC you will never, ever know how many problems you've been having.
I use ECC in an older dual Athlon MP system with 2 GB RAM. It detects a single-bit correctable error almost every week.
Living at 7,200 feet as I do increases the occurrence of bit errors in memory but even at sea level there will be some.
Now just imagine it, you have data cached in your 4 GB of fast cheap RAM as you are editing it. Some bit changes and then that data is written back out to disk. Oops. Now it is corrupt forever.
Or some bit changes in a OS kernel data structure or code and your system locks up.
Why let that happen when you can spend a little more to avoid it?
