I would guess that the Dothan upgrade can be expected, as both the LV 1.4 and ULV 1.1 models are out from Intel.
Don't know about the 60gig disk, as it's not yet on the market. But hopefully
Other improvements could be firewire support and maybe (!) better graphics.
On the other hand, also heard that IBM will wait the X4x update until the new Sonoma platform is released from Intel, expected Q1 '05. Here we're talking about faster bus and PCI-Express support, plus a few multimedia enhances such as multichannel surround.
Buttom line, I think I'm still going to go for the X40, as it's pretty much all I need. Could wish for better graphics (but no playing games on 12" anyways), bigger HDD and 2MB cache. But I guess a 250gig external hdd (for home use), a 2.5" 80gig (for the road) and a Freecom or Lacie slim DVD burner could do the trick.

And oh, plus 1gig or 1.5gigs of ram.
By the way, will I be able to feel big difference between 1gig and 1.5gigs of RAM?
This is unless someone can convince me to wait for the X41. ANYONE?
What about the IBM guys that hang around in here? Any news from your front?
Getting an X40 1.2, 512 + 512 megs, 40gb, 2x 8 cell, lacie slim dvd burner.
