I have finally ordered an XPS--got a good deal with the new coupon posted as it was stackable and combined with $250 off already offered. I got $250 +$150 + free digital camera (selling on ebay for $100) that brings my cost down to $2572--that includes wireless and 2 yr on site warranty with default cheapest config. Not a bad deal imho--sent my 4780 back last week. I am glad that I waited to order since the initial deal was a mail in rebate--the current one is instant--thanks to MVANHORNE for posting the stackable coupons. I am getting much more system and warranty for only a few hundred more than my 4780.
