Note 8.0! I sold my iPad Mini and picked it up. In a nutshell:
Better performance than Mini but $100 cheaper than Retina.
S-Pen is amazing and you'll find reasons to use it once you have it.
The Note 8.0 built off of criticism of the Note 10.1 by having better build quality and a hardware home button.
VS. iPad Mini:
Expandability (SD card of 64GB will give you more space than iPad Mini's largest size which would cost $100 more after everything is said and done and you'll STILL have more space (16+64 vs just 64)).
User customizations: Customize your home screen, use widgets. This is the general Android vs. iOS debate but it's still worth considering.
VS. Note 10.1:
Better build quality.
Hardware home button.
Higher pixel density (720p is a low resolution on a 10" but on an 8"? Just right.)
Cheaper price despite having the same hardware and a faster processor.
Lighter and better portability. You can one hand it.
It's the second version. You know what they say about revisions. The 2nd is ALWAYS better. (iPhone 3G, iPad 2, MyTouch 3G all versus iPhone 1, iPad 1, Google G1)
And vs. Galaxy Tab 10.1? It's even worse:
Better build quality, better processor, better memory, better GPU, better operating system, S-Pen, better overall TouchWiz user interface, it's an overall BETTER tablet.
Get the Note 8.0 dude. You will NOT regret it.
