I'm looking to purchase a new laptop and would like something that will play Second Life well, along with being able to pull "shadows" up inworld, as it crashes the game on my current laptop.
Shadows are very common in many 3D games, but it is still an unsupported feature in Second Life, and it is not for general use. You still can activate it through develop menu by pressing CTrl + Alt + D all togehter.
I made a film in Second Life with an ATI Graphics Card playing with some shadows, see below.
