Yea, definitely wait for a Dell deal. They offer $750 off laptops $1499 and above a lot and sometimes there are other deals below 700 bucks as well.
I just recently bought a 600M for $771 shipped and these are the specs:
1.8 Pentium M
60GB hdd
512MB RAM (1 dimm)
DVD ROM/CD Burner
64MB video
Thats about it, I love it so far and it only weighs about 5 pounds with the battery and I get insane battery life. You work on computers so you should know to stay as far away from Celeron as you can, no matter what type of Celeron it is. I would go with the Sempron over the Celeron any day of the week, but I would also go with the Pentium M over both the Sempron and Celeron any day of the week.
So IMO just wait for a good deal on a Pentium M.
