Hey guys, my Mid-2010 base MBP has 4GB of RAM. It's been kind of slowing down lately, probably because of the Lion update. However, I've also been using more programs lately (and simultaneously), so that would probably contribute to the slow down as well. Anyway, for my use, how much RAM do I need for my computer to run smoothly and seamlessly? Here are some apps that I tend to use, more or less, at the same time: Safari Preview iTunes/Spotify Mail Evernote iChat iCal Nothing really heavy duty, but periodically, I'll use Handbrake/Ripit, Skitch, iPhoto, Transmission, or Photoshop. FWIW, I usually have BetterSnapTool and smcFanControl running at all times. As for my Safari-usage, I like to have two or three tabs open usually. Mainly Facebook, Reddit, various forums; youtube every once in awhile. I'm not using too many crazy websites, but the tabs can add up when I'm researching through a bunch of online academic journals. Thanks for any help, guys.
