It cost over $100 from the computer store to upgrade my 4GB to 8GB. Took me about 5 minutes. The hardest part was removing the tiny screws from the back of the case and not losing any. This can easily be done by anyone who is comfortable with a small Phillips screwdriver. Worked great with no problems.
