Which is better, (weight/battery don't matter that much to me; mostly price)?
And yeah, any known problems with the models?

Thanks for your time!

 

What are the extra plusses next to most of them? If price is the only concern, the dv1000 or L2000 would be my choice.

 

The pluses are for RAM (from Crucial), as 512 MB will not be enough, aspecially on some with 128 MB shared video.

 

Price as the main concern, I would pick either the dv4000 or the nx6125. The nx6125 wouuld top the dv4k because of the standard 3yr warranty & HP business support which should be better than the consumer support system.

 

Power man, power. The zd8000, if you can carry the monster, is the most powerful system there. But be warned it is 12 lbs with power adapter, gets an hour and a half of battery life, and puts off a good deal of heat. It is basically a desktop with a lid.

I would personally get the zd8000, because it has all those features for a low price.

 

*bump bump*

 

L2000, you'd be hard price to find such performance in a small package. And with the Turion processor, you'll no doubt be ready for the future. I know most people say you'll replac eyour comp in two years, but I'm a college student and I need to save money so it'll probably stay with me for 4 years or more. I was also considering the dv4000, but it didn't fit into the weight class that I felt would be portable enough to carry around everyday. Nor did it offer the turion processor.
