I had the original Note 10.1 back in 2012, and I found it too buggy, plus the limited storage (16GB) just didn't cut it for me. Also the S-Pen had issues. That's why I returned it for an iPad 4, which at first worked well, until IOS7 crippled it.
Having had the Note Pro for a couple of months, now, I can say that while it was a learning curve (still is, lol) I would never ever consider going to a Note 10.1, even in the 2014 version.
Seriously, this puppy is 100% pure tech porn, lol.
And if you use the S-Pen, you'll be on cloud 9 every single time. The Note Pro is everything the the Note 10.1 should have been, with a much better display. If you use the multi screen function, you'll see what I'm talking about.
Also, accessing your favorite websites, you'll never need to use the pared down, simplified mobile version because the screen is roomy enough to allow for full desktop version which makes surfing and chatting way nicer.
Something tells me that if you get the Note 10.1, you'll be returning it and exchanging it for a Note Pro in no time.
