So, I've got this +5 year old "swivelhead" iMac. It belongs to my partner, but she says it's too sluggish for her usual work (especially compared to our 6 month old MBP!), so it doesn't get much use. Here are the specs: 800 MHz PPC G4 256 MB PC 133 SDRAM 80 GB HD GeForce4 MX 32 MB GPU SuperDrive OS X 10.4.10 Model number:M8812LL/A. She's getting random slowdowns, beachballs, and having to force-quit when running multiple apps. Would additional RAM bring this system up to speed? I'm thinking that more memory would keep it going for web, email, and document editing for some time to come. Is a RAM upgrade in this system user-friendly? I noticed from the Apple specs page that only one of the memory slots is user-accessible. Any input from you folks would be great.
