Just curious if anyone has them both and can discuss what they like or just opinions on which everyone thinks is better. It's for my girlfriend very casual stuff for work and browsing online, school etc. 

for school etc i should take the surface pro.

also does your gf prefer ios or android?

I currently have an iPad Air 2. 

I previously had a Nexus 7 (Gen 2/3?) was a 2015 model or whatever the newest was at that time. 

 

I liked the Nexus but the iPad is just so much nicer. Provided, I do have an iPhone so they do work so well together. The Nexus was nice but it did have it's little bugs like randomly freezing or taking forever to load up. I haven't had any real issues from my iPad. 

 

If if she has an iPhone or Mac then definitely get the iPad. Just do it. 

If no iPhone or Mac then it's either or. I never had a surface pro and enter used one but I do prefer my iPad overall compared to the Nexus that I had. Only thing I preferred on my nexus was that I could download a certain app opposed to having issues downloading it on my iPad - not in the App Store.
