Laptop- yea or nay?

Well all, I have raised the funds in order to buy myself one of A Compaq 2140us laptop. I'll be able to pick it up for $704, free shipping. It would put me out quite a bit of cash, but I think it could pull its weight for at least two years. My only thing that I have a problem with is that it only includes a 90-day warranty. A 2-year non-accidental warranty will cost me another $100, and I don't know if they'll have them in stock (or on sale) after that. (It'll take about two months to raise $100) So, I'm asking you guys. How are the new Compaq laptops in terms of reliability? Is it going to die after three months, or will it last its usefullness lifespan?
I'll probably make a final decision soon, and *any* opinions would be appritiated. Thanks in advance.
