The only Apple software I use is the operating system. Everything else (including the core utilities) are third party. Google Docs for word processing&#x2F;spreadsheets, BusyCal for calendaring, Chrome for web browsing.<p>I may occasionally fire up the core Calculator app but with Numi in my menu bar and Alfred a quick Option-Space away, I rarely even use that.<p>Having been burnt by Apple disregarding other software I&#x27;ve been a big user of in the past, I&#x27;m not going to let them do it again.
