Please, only actual Mac users who own an iMac should respond. I currently have a mid-2010 27" iMac which still is functional but showing it's age. The 27" was necessary when I was working but I've retired. I don't need big spreadsheets open while I am working on database builds. So I'm going to opt for the 21.5 " My needs are simple... Small Excel or Numbers worksheets; email, light web browsing (3 or 4 tabs); iTunes etc. However I am a Logic Pro X user recording mostly guitar projects. Very few 3rd party plug-ins but using Logic's software instruments, and EQ, compression and effects. Probably a maximum of 16 tracks. I've basically decided to buy an iMac from the current offerings. Does this configuration make sense in terms of getting 5 to 6 years out of the new purchase. 16 gb RAM 256 or 512 gb SSD FHD (non-Retina) 2.8 GHz quad core or Retina 3.1 GHz quad core I can't decide whether retina is worth it since I only use iMovie and do very minimum work with photos. Opinions, suggestions?
