Why no M6600 with best discount & new CPU's?

Here is the latest on M6600 with 2760QM, 2860QM, & 2960XM in U.S. Dell Small Business:

You can configure an M6600 with any of these processors only if you choose the configurations with the discounts of $619 and $604.

DELL WILL NOT LET YOU CHOOSE A 2760QM, 2860QM, or a 2960XM WITH THEIR $827 DISCOUNT. WHY NOT DELL?

If you choose the configuration with the $619 discount, you can choose:
- - the 2860QM, the 2760QM, or the 2960XM processors
-the FHD 1920x1080 display for an additional $85 (which is my strong preference)
- However, under the $619 discount, you cannot choose two 750 7200 rpm Hard Drives (my strong preference) and you do not get the better $827 discount.

If you choose the configuration with the $604 discount, you can choose:
- the 2860QM, the 2760QM, or the 2960XM processors
- However, with this discount, you CANNOT choose the FHD 1920x1080 display
- Under this discount, you must choose between the 1600x900 display, the PremierColor IPS RGB for an additional $550, or the 1920x1080 display with Multi-Touch/Stylus for an additional $350

If you choose the configuration with the $827 discount:
- you can choose all of the options available for the M6600 EXCEPT FOR the 2760QM, 2860QM, or the 2960XM.
- WHY DOES DELL NOT MAKE THESE PROCESSORS AVAILABLE WITH THE $827 DISCOUNT ALONG WITH THE OTHER M6600 OPTIONS (such as all of the screen options, and all of the hard drive options, not to mention all of the RAM and video card options)?

Why are you doing this to your customers Dell?
