My father started having troubles with the computer so he gave it to me. I reformatted the hard drive (I found he had infected it with a nasty virus) and fixed it up. It has run so well that I have even put upgrades into it. I have had no troubles with the computer and have been using it for everything from school to writing reviews on viewpoints.com. I have never had to take the computer into a computer repair store or repair it myself (aside from the virus my father got on it) and I have been using it since. Great computer. Ease of Use Windows XP makes the computer easy to navigate. The computer allows me to do things my earlier laptops couldn't even imagine doing because of its ease of use. Battery Life It tends to last two hours. The life of the battery itself is about 8 years. Support & Service I have never had to contact service on it. Speed/Performance I attribute this to my modification of the hardware but it performs very well and takes no time at all to surf the web. Design I love the design of this computer. My favorite part is the programmable led lights on the front and the XPS logos. Great look. Durability Has survived everything. From rain to drops this computer has seen it all.
