Personally I would not get all sweaty about it. I am sure it is a celeron 2ghz which they run sales on at dell all the time. And its just the 14" screen etc. So all they have done is bought straight from Dell, marked it up $100 or $150ish and are selling at.
If you watch here

and

you will see a better deal in no time..plus probably with a 15" screen.
