there is still one frustrating factor that spoils a little bit this rosy picture. Unfortunately, Intel Core Duo processors have very limited life cycle (and as a result popularity cycle). In the coming fall they will no longer be the latest and greatest mobile processors any more. New dual-core mobiles solutions that are currently known as Merom will be coming out by then. And this fast generations switch has its reasons. The thing is that today’s Core Duo processors have one serious drawback: they do not support 64-bit EM64T extensions. Therefore, when the new Microsoft Vista operating system comes out next year, all today’s advantages of Core Duo can fade away. Although Vista will support 32-bit as well as 64-bit processors, its will be optimized for more advanced CPUs, of course. So, Core Duo processor owners may be quite disappointed in the long run.

Summing up everything we have just said, we can conclude the following. If you need a new notebook, then you have to take a look at the new Centrino Duo platform. It is a good choice as of today, although it is not going to be a good long-term choice. However, if you already have a previous generation Centrino notebook, it doesn’t make much sense for you to upgrade to a new Centrino Duo today. It would be best to wait until fall and get a notebook with the dual-core processor supporting 64-bit extensions of the x86 architecture.
