My Mom has an eMac (2005) Power PC G4, 1.42 GHz, 1GB DDR SDRAM memory. It is pretty slow, and occasionally gets the beach ball. Running OS 10.5.8 Leopard. I've used several "clean you Mac" type programs to some success. Memory can be increased to 2 MB for about $50. She uses the PC for web surf, on-line ordering and banking, and email. Do you think she will notice a difference with the upgrade? BTW...I'm really proud of my Mom. She's 87 and using the eMac! Thanks!
