I'm looking to buy a base model refurbished 27" iMac for about $1200. Would this be a bad idea? This will be my first Apple desktop and I am afraid of it being sluggish for today's standards and maybe the resale value as well. Specs are: Originally released May 2011 27-inch LED-backlit glossy widescreen display 4GB memory 1TB hard drive 8x SuperDrive (DVD±R DL/DVD±RW/CD-RW) AMD Radeon HD 6770M graphics with 512MB memory Built-in FaceTime HD camera Could I get any opinions on this please? I am really interested in this computer for the monitor and the price. It would be used for music, music editing, 1080p movies and browsing.
