In secure environment, you won't
a) be patching your OS to violate the licensing terms
b) be upgrading motherboards on machines whilst using Retail (i.e. not VLK) licenses
Really, i fail to see why people are getting worked up over this.
Foocorp releases Product 2.0, with snotty licensing terms. Either the product is worth the financial outlay and licensing peccadilloes, or it isn't. Whether the company and product are MS with Windows, or Gaussian Inc with G03, or whatever, doesn't change the very simple binary choice over whether a product is worth using or not.
If you don't like the new licensing terms in Vista, then you're saying Vista isn't worth the licensing woes, which means you don't want Vista, which means you should run something else.
Simple, no?
