When I moved from Windows to MacOS, I tried to find MacOS applications to replace the ones I used on Windows (just like everybody). The more I tried, the more I found out that I should go for apps designed specifically for the MacOS, as they were more streamlined than the ones made for Windows and then converted to the MacOS. Anyway, I found out some truly useful MacOS apps and which have great functionality. Some of these apps have features which are not shared by any Windows apps (or at least it seems to me). If I were to go back to Windows (just to make it clear: I'm not), would I be able to replace the MacOS apps I use with Windows apps with the same or similar functionality? I'd like to make this a kind of game in order to find out which MacOS apps are non-replaceable killer apps. Here's my list: - Pages: a word processor with desktop publishing capabilities; - Mellel: an academic word processor, with features designed to long and complex documents formatting; - Scrivener: word processor for creative writers; - Bookends / Sente: bibliographic manager that finds out the information on already existing PDFs on the Internet; - Papers: organizes PDFs; - DEVONThink: information manager, sorts information, give suggestions on searches and has OCR features to make PDFs and images searcheable; - DEVONAgent: searches the Internet to find out information in an organized way; - Skim: PDF reader which lists notes in an organized way; - OmniOutliner / MacJournal: outliner. What Windows apps are similar to the ones above? Feel free to add your own apps to the list.
