How much RAM is it normal to use in day to day activity? When running safari or Chrome, preview and word/excel, with 8GB of ram, I'm regularly having only 4-5 gigs free. If flash gets involved, Safari eats up roughly 2GB of ram (sometimes less, sometimes more), and when flash is running, flash taking up about 1.5GB, and my free ram dips all the way down to 3.5-3.8 sometimes. Is this kind of usage normal? I don't see how this could be normal, as those with 2-4GB would be unable to run 3 basic programs if this were the case. I got this much ram for when i'm doing audio production. I didn't expect to be using 50% of it while web browsing and writing documents.
