Meddude - glad you found a good laptop FINALLY
but on the UPGRADE thingy - in 1-2 years PCI Express will be the thing of the future...and current motherboards are not PCI Express ready.
You will be FORCED to either take or leave an upgrade in the next 6 months which itself is not a bad thing but its not a good thing either.
So dont count on the upgrade as a BIG decision behind your purchase...thats just plain silly.
The 9100 is similarly powerful for a LOT less money...
