Old Macbook didn't have enough RAM (1GB) to quickly access the the Internet and process applications.
VERY EASY - The new RAM (2GB Total) arrived on-time and was quick to install following the IFIXIT instructions with pics. Took me less than 15 minutes!
My tips are:
1. Make sure when you remove the existing two 512KB RAM boards, you note the top vs. bottom orientation so the new 1GB RAM boards are inserted in the same orientation.
2. Make sure you insert the new tow 1GB RAM boards very firmly.
3. Once everything put back together you can check to see the new total 2GB RAM is seen by starting up your Macbook and using the "About this Mac" option under the lefthand apple icon.
