I have a 2006 model 2.16Ghz 2MB RAM 24" white matte screen iMac that's served me well but has considerable dark gray screen burn in spots and is showing its age by running slow. I will only buy a non-glossy, non-glass matte monitor/screen as the reflections from a glossy screen would drive me crazy, especially considering the room the computer will be in. I have read conflicting reports on whether or not the 2013 and 2014 iMac is a glossy, glossy-light or matte screen. Wikipedia indicates "Glossy glass-covered widescreen 16:9, LED backlighting and IPS technology." This makes me wary. I don't want to see any reflection at all, especially since I sometimes spend a long time in front of the screen. If the new iMacs don't have any reflection, then would a 24" or 27" be better for me? If the new iMacs are indeed glossy screens, then is there a 24" or similar sized non-widescreen matte monitor that would be similar to the 24" white iMac screen? I do not like true widescreen monitors, where there is hardly any vertical. I consider the 24" white iMac to be a compromise or middle ground between 4:3 and 16:9. I don't mind going the Mac Mini route. Is there an advantage to buying an iMac or Mac Mini via the Apple refurbished store vs buying a 6 month old unit via a private party on Craigslist that has an Apple Warranty? I truly wish I could purchase a 2006 model White Intel plastic 24" iMac again but since computers don't have odometers so to speak , there's no way to tell how many hours they've been on or used. I would buy one that's been sitting in a closet for years, though there's no way to verify that statement.
