look at the tread simular to this. If dell still has the $-500 off discount with coupon, id get the 700m. i posted it on a simular topic so you just need to scan though it. But the total price of the laptop shipped to the door and after taxes came out to 949.00. I dont think thinkpads can come close to that deal and this is spoken from a thinkpad user. The thing also is if its a for a girl, i doubt shes gonna want to carry around a 5-7lb laptop. The dell is about 1/3 smaller then the T series and maybe about 1/2 smaller then the R. Also there giving away a free DVD-/+RW drive.
PS. Thinkpads in general except the X series are under regular portible catigory, The X is ultra portible. The Dell 700m is right on the margin of ultra portible to regular portible.
