Windows Vista Vista OEM Purchasing

I read Arie's article on which version of Vista is best for individual needs. I also have read other online articles related to the same topic.

I would like feedback / suggestions related to purchasing Vista OEM Full Version (at a minimum Home Premium OEM).

I have read that you cannot reactivate with motherboard change, and I have also read that you can, so I don't know which is correct.

I have also read that Microsoft uses a ten point check system to link an individual computer with a particular license of any Windows OS. Mainly hardware components installed on that computer.

So, my question(s):

1.) How many, and or, which hardware components can one change on a computer before Microsoft/Windows disallows a reactivation of the Windows license for that particular computer.

2.) Is it true that any change to a motherboard will invalidate an installed OEM version of Vista (not allowing reactivation), or any version of Windows for that matter?

3.) I am one who reformats at least 3 times a year. Will this cause a problem with reactivation?

4.) Is OEM a watered down version, or full version? All I have read would indicate that it is a full version, just without the fluff of nice packaging and documentation or support.

All comments and suggestions are greatly appreciated.
