I'm going to be getting a laptop within the next month. But I'm not sure about what processor to get. The laptops I have looked at have the Pentium-M Centrino, the Mobile Pentium 4, and the Mobile Pentium 4-M. Are any of these processors upgradable in laptops? And what the heck is the difference between the Mobile Pentium 4 and the Mobile Pentium 4-M?! the only difference that I have been able to see just by looking at the laptops is that the Mobile Pentium 4-M only has a 400Mhz FSB and goes up to like 2.6GHz and that's all, while the Mobile Pentium 4 goes up to 3.06 and has a 533MHz FSB. Am I right here? To me, there would be no point in getting a laptop with a Mobile Pentium 4-M then...'cause that's kinda older stuff. And is intel going to be moving mostly to the Pentium-M Centrino? It costs a lot of money for a laptop so I want to get the best deal. If the Centrino is the future AND they are upgradable, than I will definately get that. Bah, it's all very confusing...hopefully someone has some answers to my questions. Thanks in advance!
