In response to my post over in the Buyers Tips section, there is a things I'd like to know about applications. I'm brand new to Macs, so I'm not exactly up to scratch on what's the best application for individual tasks. The main tasks I'll be carrying out on the Mac will be web browsing, chatting (both IM's and IRC), web development, word processing and other of the usual office tasks. Can anyone suggest a few apps that'll cover that'll meet my needs above?. Plus, is there any other neccessary apps I should know about? Another thing I'm not to sure on is Anti-Virus and Firewall. Now being a PC user for all these years, having an AV and FW is essential. But what about with a Mac? I know Macs are well known for there virus free ways, so does mean I don't need to worry about an AV and FW? Thanks for your time, much appreciated.
