I'm looking at a 2011 27" iMac 2.7 GHz 8GB RAM 1 TB for $625 vs. a 2012 13" MBP (non-retina) 2.5 GHz 4GB RAM 500 GB for $450. I'm wanting to buy this computer for general web use, typing docs and the like, watching videos, and doing some light development work. I have a gaming PC which I intend to keep for playing games, but I'd like to make the switch for my everyday tasks since it looks like Microsoft is destined to shove Win10 down everyone's throat and I've had the last straw with the way they're pushing it and putting ads in (even if all can be disabled). I don't especially need the computer to be portable, but I don't have a laptop besides an ancient ThinkPad that runs Lubuntu (which is just for messing around with more than anything). I do have an iPad that has seemed to work ok in a pinch when my gaming PC went out, but that was just for a week. I would be using this computer 95% of the time plugged in sitting on my desk, but the nice part would be that I could take it somewhere if the need came up. As far as the iMac goes, truly a 24" iMac would be the better size for me for the exact spot I want to put it but I can fit a 27". I've heard the 21.5" is harder to service too, so I have my hesitations for that reason. I have a 30" display (2560x1600) that I would be running as the main display with the iMac being a second screen if I went that route. If I go with the MBP, it would be closed and going directly to the 30" screen. So with the MBP I will need either a USB switcher for my keyboard/mouse or an Apple keyboard/mouse to use with it. I could afford to buy a new iMac or MBP, but I'm not sure how committed I am to making this switch so I don't want to put that much into it yet. Since Sierra removed some support for devices, I'm always afraid of the eventual cutoff from Apple where it gets no new OSes and that's what I want to avoid. Performance wise, I think the 2011 and 2012 are both plenty fast enough (though I'd probably have to put in an SSD in either, long term). I have a relative running a Thinkpad T420 from 2011 and it has no problems and I know it could have Win10 installed and keep on trucking for many more years. My ancient Thinkpad is a 2005 and works perfectly besides being not good at playing web videos. So that all said, which would be supported longer - the 27" iMac or the 13" MBP?
