Hi, I am in search of a new laptop and would definitely appreciate some help. I have a pretty good idea about what I am looking for and could use some advice. I have read some of the info comparing the processor speed, power usage, etc. but I am looking for some real world experiences and advice. Is there much of a difference between a P4 2.8Ghz and a Centrino 1.6? I am looking for a light-weight portable laptop with good battery life, and am inclined to go with the Centrino. I use fairly simple applications, MS office, other database/spreadsheet applications, so my guess is I won't notice the speed difference. Also, is it a good idea to buy an off brand computer or am I better off sticking with Gateway, Dell etc.? The prices are often appealing, but I am concerned with the ability to find replacement parts down the road. Any help would be appreciated. I know what to do with a computer once I have it, but I'm not real sure how to go about getting my next one Thanks!!
