I have a 24" iMac 2.66 Core 2 Duo, 4 GB ram, 640GB HD. I keep iTunes, Twitter app, Chrome, Mail, and Finder open at all times. For about the last 3 weeks I've been noticing an excess of spinning beach balls. A LOT more spinning beach balls. Also, tried to help a family member out by enhancing her photos in Photoshop and it kept hanging up, basically Photoshop and other CS programs are now useless on here. I only have about 30GB's left in my stock HD and have been putting everything on an external for a few months. Also, I have been noticing that my internet hangs up, never did that before. I have FiOs 25/5. Never had a problem before, but since their Quantum debuted, it's been a problem. (Throttling?) I'm not happy how things are working now, do I need a new computer, or do I need a new internet plan? Or, both? I cleared out non-essential applications a few months ago.
