You are correct. It only has 3 usb ports,64MB shared graphics and no firewire. A little birdie says that PCW came to know of this error and were instructed bt Headquarters that the POS was incorrect. the stores were instructed to remove the original POS and make a new POS to state the correct configuration.
If the store you bought from has not changed the POS, best wait to see what the members of this forum advise. You can request a refund if you wish.
Have bought this model for 2 people and overall the build is very good and the screen superb.
