Hey everyone. Long time lurker, first time poster. Anyway, I just thought I would say that I finally have my Blackbook, after months of waiting. I couldn't be happier. This is such a wonderful machine! The specs are: 2.2 C2D SR 160 GB HDD 1 GB RAM GMA X3100 I am going to be upgrading to 4 GB of RAM next week or so, (third party). Will I notice a HUGE difference from 1 GB to 4GB? With 1GB it is pretty fast but I like to have several apps open at once, so Im sure I will notice a difference. Also, I downloaded Google Earth, it is a bit laggy with 1 GB of RAM, will it stop lagging with 4GB? I just thought that maybe Google Earth is a bit of a resource hog. Anyway, thanks everyone!
