Even Microsoft's native applications can feel off. For example, I use Outlook for my email and really dislike its editor. When I type, I want the text to snap into existence immediately as I type. In Outlook it feels like it glides into being and doesn't even keep up to fast typing. Word is like this too, but fortunately I don't have to use it very often.

Because of this, I write longer emails in a text editor and paste it into Outlook when I'm done.
