    I'm currently using OS X 10.5, and intend to upgrade to 10.6 in the fall. I'm using a Santa Rosa Late 2007 MacBook, 3 GB RAM. When I upgrade to the fully 64-Bit Snow Leopard, will I be able to surpass the 4 GB RAM limit, or am I bound by other hardware limitations?

    I would say it's hardware...

    Yeah, if you're upgrading your current Macbook, you can't go over the 4GB limit, that's all the hardware can do. The new Macbook Pros can do up to 8GB of RAM though. You should check those out.

    I have heard of some people getting 6 GB of RAM in their white Macbooks. Not sure how well that works out though.
