Have reviewed some of the past discussions on this topic and I'm keen to get my Mac feet wet. I'm looking at buying a used model - my req's include DVD, Web surf, music, and potentially TV??? (will keep my PC for "Work type activity for the moment). Are there any particular hardware faillings on the "DV" models I should be aware of and what about the TV application. Do iMac's make a good portable TV (Free to air and cable)? And if so any recomendations on tuner hardware (No high end editing required - just watching)?
