Summary: I purchased the W500 Thinkpad when it was released in 2008 and it's still going strong. This was my first Lenovo computer and it's been such a good experience that i just recently purchased the Lenovo Thinkcentre m92p desktop. I now basically always look to buy Lenovo first. I'm a technology worker and i can assure you that i put the w500 through it's paces, running some of the most demanding software on it such as the Adobe CS suite, Microsoft Visual Studio and more.
Summary: Well it is an entry level workstation, but has a professional graphic card not the gaming one. Basically the different are the drivers. I think 15" widescreen is the good balance between portability and getting some work done on a good size screen. The version I ordered from Lenovo is almost max out with the newer technology. I use N draft at home with 5 GHz frequency. When I go to a coffee shop I have no problem connecting to G and B routers.
