Ramseeker
One of the best ways to make your Mac better is to buy more random-access memory (RAM). RAM is the readily available memory that your computer uses; the more you have, the smoother programs run. Although OS X might run on a Mac with less than 2GB of RAM, it works much better and faster with more than that — at least 1GB, in my opinion. As cheap as RAM is today, the price that you pay for it can still vary quite a bit. The best way I know to get the lowdown on RAM prices is to use the Ramseeker feature of this site, which surveys multiple vendors daily and then organizes current memory prices by Mac type.
Figure 23-2 shows how it works.
