I just received my new 20" iMac 2.16 Core 2 Duo. I love it, or want to love it, but I've noticed that it's really quite slow when doing things like switching applications, starting new ones, and sometimes just completing basic tasks like opening a file from Word or getting the print window to open. It took no less than 15 seconds to switch over to Dreamweaver, for example, and all I had open was Word, iChat, and Entourage. That's really not a lot. The hard drive seems to be running constantly as it completes these tasks. This was one of the reasons I bought the computer - I hated these annoying little slow downs that occurred when doing basic tasks. (don't get me wrong, when I'm encoding video, this machine blows my old eMac away). Is this because I'm still at 1 gig? My eMac had 768 MB and wasn't this slow. Does the Intel processor demand more RAM? I was hoping to hold off a bit. Any ideas?
