Definitely - a lot of apps and sites don't have the full features of programs on the desktop still. Well, I do use a laptop more now, but still consider it more of a desktop due to it's size.
As for functionality, for example, I use Canva to create images for work, but not even my tablet has all of the features available, according to the site when I log on and when I try to design. Also, even MS Word doesn't have all of the features I use when editing with track-changes and such. Or they are hard to use even with a stylus. If I could edit from my mobile phone and show my work, I'd rarely get on a desktop!
