Hey all. I need some input and advice please. I know right where to come. Within the next few months, I will probably be getting a new Laptop computer. I have a few questions about Intel's various processors and need to know the difference. I get that the Mobile Pentium 4 is like a desktop with some differences, like it can slow down to save power etc. But there are other laptop processors I keep reading about lately. What is a Pentium M? What happened to the Centrino's? I noticed that those 2 only goto like 1.60Ghz or so, where as a Mobile Pentium 4, can almost reach desktop speeds. Are the Pentium M/Centrio Procs measured differently? My laptop which will be 4 years old in September is a Dell Inpsiron 8100, It's a Pentium III 1Ghz. 32 Meg Video card, and so on. I'm looking for a good upgrade, one that will last me a goodm few years (I do not need or want top of the line but I would like it to do SOME things. I have a powerful desktop for gaming so I do not need a Laptop to match, but I would like it to have some power. For reference, having it being able to run World of Warcraft well would be perfect. That would be the only game I would play on the go. I'm looking at $1500 most to spend. Brand does not matter much, but which of those processors would I want in the system I am looking for to be able to do what I want it to do? Thank you for your time.
