After a week hands on with the Macbook, I can safely say it will take anything you throw at it. As an example here is my daily workload: I am a heavy user of Spaces, so I typically have 4 running at any given time: 1 for Fun 1 for Business 1 for Messages Tweetdeck(having its own full screen space) I usually have the following programs open at all times: 10-15 Safari Tabs open 2-3 Pages documents 1-2 Numbers spreadsheets 1 VM(I have both Windows 10 and Ubuntu 14.04 installed) Occasional Photoshop iTunes Radio I also have been running games in my free time: Kerbal Space Program(with a few seconds load time between switching what I am doing) Mostly indie games Steam Home Sharing has been a god-send for running other games at very high quality. I was very skeptical when the specs of the rMB was announced, as I consider myself a power user and run an IT company. My biggest fear was not the ports, but the power. It has well and truly exceeded my expectations and I have not run into a single situation in the last week where I went damn this thing is underpowered. I knew I would have 14 days to test this in real life and see if it fit my needs or I would return it. This laptop is going nowhere(unless I sell it to upgrade next year). Note: I understand there are users who require more power than I do, such as full-time video, photographic, and music editors. I am not one, so when I use Photoshop it is not for intense 4K imagery, but usually less than 2000*2000 pixels for short durations of time and I have yet to run into an issue. I could see how this would not be powerful enough for some, though, hence the qualification plenty of power "for normal users".
