For me, it's all about the S-Pen and the sdcard storage. I was on the verge of buying a Dell Venue 8 Pro but after seeing the reviews ad forum posts about the poor stylus experience, I decided on the Note 10.1 2014.
When I travel for my job (which is often), I carry three things in my backpack: a laptop, a tablet and an A4 notepad with pen. I take a lot of notes and end up with pages and pages of stuff that I either end up losing or having to transcribe to digital documents. My plan is to drop the need to carry a notepad with me.
I also watch a lot of tv shows and movies when travelling and the possibility of a 64Gb microsd card stuffed with media will be a welcome relief over deciding how much I can fit onto my current Nexus 7 which shares it's 32Gb capacity with the OS, apps and other data.
