I feel awkward even asking about this, since it seems like such a strange and improbable idea to me. I'm wanting to buy a laptop (not notebook) soon, and I want to know how it runs before buying it. Is there any way I can get my PC to "emulate" another machine such as a laptop--so that it performs more or less the same way the laptop in question would? The idea would be to get my PC to "act like" it has the specifications of the laptop, so that I could run games and other applications to test how they would perform.
