Can an iPad Pro replace my old devices?

Hi all, I've currently got an iPad (3rd generation, 2012 model), and an old 2011 model MacBook Pro that I use for my day to day study/leisure activities.

Both are incredibly slow and annoying to use and i'm looking at replacing them with just the one device.

Is the iPad Pro (12.9") good enough to replace my MacBook and become my main computing device?

I'd keep my MacBook around to occasionally transfer files/songs, etc. onto the iPad, but I'd plan to use it (with a keyboard) for all of my day to day tasks. Are iPads really advanced enough to be able to replace a laptop nowadays?
