I have two computers: 2011 iMac 27" base (1 TB HDD, 12 gb ram, etc) 2011 Macbook Air 13" base I'm considering selling both and replacing them with one computer: 2012 Macbook Pro Retina 15" Base Advantages: Consolidation Newer chipset (faster?) USB 3.0 Gorgeous, high res screen with option to add an external monitor Better GPU then both iMac (?) and Air Larger SSD than Air Disadvantages: No large, beautiful 27" screen Lose potability of Air No DVD drive I use my computer for: Fairly heavy Lightroom image editing (currently with multiple USB 2.0 external drives). RAW files, scanned TIF files (50-100 mb), etc. Web browsing, iTunes, etc Very occasional video editing Occasional gaming Thoughts? Why wouldn't I do this?
