The HP ZT3000 Series Notebook can be categorized as either a desktop replacement notebook or a mid-range, thin and light model. Because it comes with an Intel Centrino Mobile processor rather than a Pentium 4, the ZT3000 is really made for portability. It is only 1.3 inches thin. However, It’s large 15.4-inch widescreen makes the notebook too large for practical mobility. Personally, I was more concerned about performance than how large the notebook is; therefore, the ZT3000 was the ideal choice for me.
