So I just bought an entry level iMac 21.5...and I'm getting the beach ball a lot. my 13" Macbook Air entry level will run circles around it. Just bought both of these in the last week. What's the deal? Is the SSD that much faster? I'm a pretty intensive power user, and I'm wondering if I made a mistake buying the iMac, and if I'll need to return it. If it matters, I'm running an external 24" Display, Photoshop, Web Browser, Skype, and that's about it right now. What gives!?
