I need to replace my 2006 iMac as is is having issues. My debate is to get the next iMac or to just get a mini and nice monitor. My wife does the basics - email, online shopping and banking, etc. I use my iPad for those things. However, I want to get back to using iMovie and IPhoto. I have read a lot about the lack of discrete graphics in the mini. Will that be an issue for iMovie editing? I am not a gamer. Any advice?
