Apple should not do this...
Apple make good computers, they use good components etc. They just happen to be based around a PPC instruction set. If you want to run windows on your Mac, then write a nice letter to MS and ASK them to compile you a Apple / PPC version of windows.
Remember, Operating systems are designed to run on various hardware. NOT the other way round. Thus, the decision of which hardware you buy is based on which OS you think will give you the best features for your needs.
There are plenty of very good, very well designed Wintel machines around. Remember
You are not going to find these machines at your local PC World / Walmart. These companies are interested in 1 thing only... the Sale!!! The quality of components comes second only to how much markup they can make on a particular brand.
The best advise is to make your own!! get onto Google
and hunt down the components and reviews on the quality if these components...
Here is a start, Crucial RAM, MSI Gfx cards (nVidia / ATI chipsets) ABIT mobo's (Intel / nVidia chipsets), Maxtor HDs. etc...
These are based on continuous reviews of good quality... Not the fastest or newest! It is possible to build a "PC" as good as quality as a Mac, but you will always ruin is by running windows!!!
An even better idea would be to write a letter of complaint to the manufacturer of DVD's stating that there are many cross platform multimetia applications (Flash / Shockwave), Java etc, and that you are very dissapointed with them and would have to take this into consideration before buying their products again.
If we all just sit here moaning on forums, these companies are never going to support OSX
