Common sense would tell you not to compare apples to oranges. so why would u do that with sd screens to he screens?? I mean obviously thenhd screen will be better. If I compare a iPhone 3GS to an iPhone 4s of course the screens are gonna look different.
As for the stylus. That's a matter of your opinion. I've used stylus on both tablets, and have seen no difference on either screen. If you are seeing a diff, maybe you need to clean your screen. But honestly, I'd much rather use my finger. Even in class taking notes. I agree that a tablet can be a replacement for a binder, but I can just as easily use my finger to write as I can with a stylus.
In app purchases are stated on the store?? Them how come I've downloaded lots of "free" apps only to find out the functionality I wanted requires an in app purchase?? And all of the apps I use on android I have gotten either free, or severely reduced. The apps may be on sale, but not nearly as much as android. 10 cent apps, free apps, 25 cent apps, I'll take that over reducuced to 99 cents from 4.99 for the iPad version everyday. And what's with diff versions for most of the iPad apps?? I'm still trying to get used to having to purchase diff apps for phone and tablet...
