I just picked up a 8.4 Samsung galaxy 4 PRO for a gift. You will save money over the S version and the S yields nothing better, from what I can see.
The PPI for the 8.4 pro is among the best on any tablet....same as the S version. The pro processor has a 2.3 quad core 2gb ram. The S version has an edge with 3gb ram...but that's about it.
The tablet is very responsive and looks cleaner than my ipad retina.
The ipad is great, but overpriced and unless you're using Apple specific apps...the Samsung 8.4 pro is an impressive tablet. I was open to the S version, but it wasn't worth the $100+ difference. It's newer, so that's the main reason for the price jump.
Hopefully I save a get bigger $100 today. Haha
I'm not sure why people on this thread had no use for their ipad. It's a great tablet...overpriced, but still very good. The number of quality apps is impressive and the operating system is solid and smooth.
It's great for music, porn, general web, email, music streaming to Apple TV, etc. how can someone not like it?
