Based on my research and experience, here are the top desktop replacement laptops that use 17-inch and larger screens. Desktop replacements are one of the largest growing segments in the portable market. These system pack in the features and functions that make them competitive with full sized computers. There are even a lot of specialized multimedia and gaming models.
For the past year, Lenovo has been offering some very strong values in their P series laptops. Their latest model, the P-7807u FX has a list price just $1099 but you get a lot fro this. It comes equipped with an Intel Core 2 Duo P8600 processor, 4GB of DDR3, 320GB hard drive. While it comes with a fairly powerful NVIDIA GeForce 9800M GTS graphics processor with 1GB of memory. It also is relatively heavy for a 17-inch laptop weight in at just over 9 pounds. Still, dollar for dollar it is one of the best values on the market today.
Their latest version of the laptop comes with the new Intel Core 2 Quad Q9000 quad-core mobile processor that allows it to handle multitasking and multithreaded applications better. Those that need to store lots of applications files will be happy to see the 500GB hard drive. Multimedia fans will be thrilled to see the Blu-ray combo drive and 18.4-inch 1920×1080 display allowing them to watch high definition videos.
