Some of the things that I found interesting:
* Both Core Solo and Core Duo CPU options
* IEEE-1394/Firewire Connection
* Serial ATA harddrive (SATA or S-ATA)
* Apparently an internal optical drive (CDRW or DVDR)
* Optional Widescreen/high resolution (1400×1050) display
* A capacity of 4GB of memory
* Dual Channel memory support
* Expanded internal flash memory card reader
Combine the 4GB of memory, Core Duo CPU (upto 2.16GHz), high resolution display, Firewire connection, SATA harddrive, and DVD burner, and you have an ultraportable video or photo editing machine.
