I'm thinking about getting the 20" iMac. I've never had a Mac, so I have some questions. I want it to replace my TV, stereo, and DVD player. To watch TV on the iMac, would the eyeTV Hybrid be fine for that? Is it easy to use? Also, how good are the speakers on the iMac? Since I want it to replace my stereo, would it be better to buy separate speakers? Lastly , can the iMac play DVDs from any region in both NTSC and PAL formats? Thank you for any help.
