I'm on Mrs. Dual's Satellite L355D, which is pretty impressive for being only $399.
It's not very portable, It's more of a desktop replacement unit, with a 17" display. The keyboard is offset to the side a bit, because the large display laptops have room for a numeric keypad.
Mrs. Dual is heavily into scanning, and Photoshop Elements and Premiere Elements, and she is finding that heavy image processing is sluggish, but that would be the case for most any laptop. And with the march of technology and chips, it does still get the job done.
Having experienced the old Satellites from the 90's, and this one here, I think it's a perfectly adequate machine.
