If you use computers "a lot", the percentage of time required to learning a select few Linux userspace administrative tools, as well as the time dedicated to configuration and maintenance, is less than nothing compared to time spent on general everyday usage. The common perception that Linux is a timesink is false (not to mention most things are very much plug-and-play nowadays, e.g. networking via DHCP). And the benefits in doing so are huge, in that you now control your needs using a variety of independent tools, as opposed to the far more locked-in, proprietary solutions that Apple offers. I simply disagree with your claim that Macbooks are the best option for so-called power-users when on multiple aspects from hardware to software they're not. Macbooks/The Apple ecosystem is A choice, not THE choice.
