I purchased my mother a white MacBook 6,1 several years ago. She's retired and she only uses Firefox. She is as far from a power user as they come. This laptop is in extremely clean condition. It is stock: 2 GB RAM and a 256 GB hard drive (60 GB used). Snow Leopard. The MacBook is getting very slow, and the trackpad doesn't click well. I tried to adjust it, which helps a little. I think part of the slowness is the trackpad, because it doesn't always register clicks. I am extremely proficient around hardware. So I could replace the trackpad ($50), upgrade the RAM ($50) and install in SSD ($100). But if I spend this $200, will the performance be worthwhile? I could instead purchase myself a new Mac and give her my MacBook Air, but that would be more expensive. Thank you in advance for your suggestions.
