Yes the touchpad is offset compared to the system itself, but it is actually nearly centered to the main keyboard section - which is where you want it to be. Thank the addition of the num pad for that.
I have just gone through the entire manual for the system. EVERYTHING is modular in this thing, which is a big plus for Dell and the users. The audio jacks are on their own little board finally, so no more entire mobo changes just to fix the broken crackly sound anymore. The physics card and CPU share a fan, and a two piece heatsink assembly. BUT get this... the CPU is UNDERNEATH the mainboard! How wonderful that is for potential cpu swappers

Other things of interest... Digital Array Microphone - basically a right and left channel mic assembly that lets you simulate a 3 dimensional recording. Limited value to an avid gamer I suppose (unless you want to sound like Zeus to your WoW buddies while raiding...) 2MP webcam in the bezel, supporting 10FPS vids at 2MP, and 30FPS at VGA quality. Of course the gaming LCD, which is designed to display pertinent info from the game you are playing at the time (can see this being used by a WMP or Winamp plugin to display song titles in the future)
There are 3 MiniPCI slots total in the system, though not all three can be used with the same card types. There is a dedicated WLAN slot, which will ONLY work with a Wireless network card. There are 3 antenna wires associated with this slot for either a/b/g hookups (2 wire) or with a draft N type card with the third aerial for MIMO. The second slot is designated for a WWAN card (broadband access type card from a cellular carrier) and there are two antenna connectors dedicated to this slot. The WWAN slot can also be used for FCM aka the Intel Flash Cache Module aka Robson. The third slot appears to be a basic PCI-E 1x slot that could likely house any card (more than likely it will support the Wireless USB standard once there are cards for it.)
32GB SSD (Solid State Drives) appear to be included as an option now too. It'll be interesting to see how many people choose this option...
Anyway, nice find Sleey0. Definately some good info on there!
