I am considering upgrading to a new iMac, I have a 20" Aluminum iMac that I bought in early 2008, but was the 2007 model. I am not 100% sure if I will buy one, but just wanted some opinions. The specs are: - 2.4GHz Intel Core 2 Duo with 4MB L2 Cache - 4GB RAM (667MHz) - 320GB Hard drive - ATI Radeon HD2600 Pro with 256MB VRAM - 1650x1080 screen resolution This iMac has been great over the past 2 years, but I can't help but feel as if it's showing it's age, even though it's only been 2 years. I only have 54.75GB of hard drive space left, and it struggles at doing certain things. The spinning beach ball is a common occurrence on this machine. I can't spend that much, so I've been looking at the refurbished store on the Apple online store. Is it safe to buy a refurbished iMac, and why are they refurbs? For $1349 I can get the 21.5" iMac: - 3.2GHz Intel Core i3 processor - 4GB of RAM (1333MHz) - 1TB Hard drive - ATI Radeon 5670 with 512MB VRAM - 1920x1080 LED Screen For $1549 I can get the 21.5" iMac: - Exact same specs as above, just the core i5 instead of the core i3 OR For $1549 I can get the 27" iMac: - 3.2GHz Intel Core i3 processor - 4GB of RAM (1333MHz) - 1TB Hard drive - ATI Radeon 5670 with 512MB VRAM - 2560x1440 LED Screen The 27" will just barely fit on my current desk, and the $1549 price for either is pushing the limit, but still doable. It's either buy a new iMac, or buy a new 50" TV. So that's my little dilemma, sorry if that was too long. Thanks for helping if you do.
