The Acer 5672WLMi is indeed a good laptop.
Dells are very good. They are at very ncie prices with very nice discounts. You can configure a much better laptop, and get a 500-700$ rebate, and you would be looking at a T2400, 1-2gb ram, x1400, 100+gb HDD, DVD burner.
You can always buy laptops with little memory and upgrade it later, as this is much cheaper. IBM have very solid build quality.
My current specs:
Biostar TPower x58
XFI GTX260 Black Edition
640 WD Caviar Black
Vista Home Premium x64
