New Macbook or iPad Air 2?

I

iMore Question

I have an original iPad Mini which has become quite slow and keeps crashing so I have decided to upgrade it. I also have an iMac desktop which is what I use for the more hardcore requirements such as video editing etc and it is my main computer. The replacement to the iPad Mini is going to be more for web browsing, emails and also for photo editing when I am travelling.

Would the iPad Air 2 suffice for this or is it worth spending a little bit more for the new Macbook?
