I've been supporting Compaq business products for the past seven years and couldn't recommend a better product. Keep in mind, I'm talking about the business line not the consumer. The laptop series is the Armada and you can configure online directly at the website. They don't come with much other than an OS since it's all business products and not retail fluff, plus their warranty is outstanding: 3 years onsite parts & labor for most models. Those that don't can get it added for less than $100. Plenty of options available as well, such as DVD/CD burners in addition to wireless LAN, more memory, upgraded graphics etc.
I've been using an N600C for a couple years now and have been quite pleased. The N800C may be the model to look at since it's newer, just find the right balance of features and pricing to suit your needs.
All my laptop users run theirs on average about 10 hours a day 6 days a week and aren't too gentle with them either. They hold up just fine and take the abuse. Plus with a magnesium case they're some of the lightest in class. Our last batch of Armadas (7400 series) lasted five years and were only replaced due to warranty and support concerns. And they were gettin' kinda slow considering they were, like, Pentium II's!
Remember, in laptops you definitely get what you pay for!
