MacBook: Apple's Weapon vs. Dell's Cheap NoteBooks

Apple has released the MacBook, finishing the transition of its notebook models to Intel CPU. It is also now easier for customers to choose a notebook according to their needs, and it makes also Apple's life easier (no more competition between iBook and PB12", no more iBook 12" or 14").
The other interesting point is the price of the new MacBook, very aggressive, and calculated to directly compete with similar notebook models from PC manufacturers, especially from Dell, as noticed by Slashdot.
Hereafter are the specs of a Latitude D620:

Intel® Core(TM) Duo T2400 (1.83GHz) 667Mhz Dual Core
OS: Windows® XP Home Edition, SP2
Display: WideScreen WXGA 14.1"
GPU: Intel® Integrated Graphics Media Accelerator 950
RAM: 512MB, DDR2-533 SDRAM, 1 DIMM
HD: 60Go, 9.5MM, 5400rpm
optical drive: 24X CD-RW/DVD w/ Cyberlink PowerDVD(TM)
Wifil (802.11): Dell Wireless(TM) 1390 802.11g Mini Card
Bluetooth: Dell Wireless® 350 Bluetooth Module

its price 1466 $, a price very similar to the MacBook (after adding the extended AppleCare to match Dell warranty)!!
Things have changed at Cupertino, and the competition seems now on, between Apple making CPU transition and record financial quarter vs. Dell posting profit warning.
As mentioned by Jesper on Waffle website, "I think it’s safe to say that whenever someone tells you that Dell’s machines are cheaper than Macs with comparable specs, they’re bullshitting you.".
Will the price of all Apple hardware models be lowered due to Intel CPU transition? It will benefit Mac users anyway.
