iBook vs. 12 in Powerbook

[Joe]

Just saw the specs. of the 12 in Powerbook from Macworld:

"New 12-inch PowerBook

smallest ultra-portable around
smaller than iBook in every dimension
slot-loaded optical
10x7 display
856MHz G4
GForce 4go
slot load combo drive (side)
BT built-in
AE ready
antennas in lid
5 hour battery life (same as iBook with G4)
4.6 pounds
boots into Mac OS X
QuickBook bundled
US$1799

shipping in 2 weeks
most affordable PowerBook ever.
BTO option: SuperDrive (US$1999)
starts at US$999"


I'm wondering, wont this kill sales of the iBook?...Perhaps at least 
should drop the price of the iBook tremendously...?
