I have an Inspiron 6400, and it's hideous!
Like with yours, the plastics are as flimsy as hell; it's filled with scratches, and some of the keys have fallen off (using USB keyboard instead)
I'm also having huge problems with the charger - it won't charge over night, which is infuriating.
Finally, the laptop keeps stuttering, because one of the main components isn't connected to the rest of the machine properly.
So yeah, can't wait to get rid of this nuisance of a machine :P
