I'm patiently waiting for my new iMac 17" to arrive. In the meantime, I'm prepping to receive it and have a bunch of questions about software. I'm making the switch from Windows! Do I need Antivirus software and if so, which one? Symantec? What's a good BitTorrent client? I think the first thing I'll be doing is working with my photos. One thing I'd like to try on the Mac is making a calendar with pictures. Can iPhoto do this? If not, what's a good calendar creation program? What other utilities will I need? What's a killer game for this platform? What other killer apps and must have software do you recommend? Can't wait!
