Hey everyone, I'm on the fence about buying an imac converting from PC. I have an older Mac G5 that I primarily use for itunes and recording music through protools. It's a great machine and have had very limited problems. Otherwise, currently a PC user for photo, video, office etc. I was thinking that if I bought an imac I could use it for everything as an all in one and dump the G5. I just had a couple of questions regarding the switch. I have an external HD formatted for PC as a backup. It contains documents in MS office format, pictures in .jpg format and HD videos in AVCHD (Sony HD camcorder). First, if I plug in my PC formatted external HD via usb, will it be recognized on the imac? This is the most important question as I'd like to transfer my PC files to the imac without a problem. I'm assuming MS office docs are compatible with MS office for Mac. I'm assuming .jpg are compatible with iphoto. Lastly, does imovie support the AVCHD format or convert it without too many issues? Thanks very much for any help you can provide.
