I own an note 2, and I'll upgrade to the iPhone 6+, the Note 4 with the exception of the S pen and the fact it's smaller, has nothing to appeal.
1st iOS / OSX are IMHO the best ecosystem, superior 3rd party software quality, years light away superior integration (hands off, apple pay etc).
2nd useless features as resolution, is not human possible to distinguish 1K (note 2) from 2k(iPhone 6+) much less from 3K (note 4).
3rd and worst : SAMSUNG HATES TO UPDATE IT'S DEVICES SOFTWARE, they only gives updated from 2yr after launch then you need to buy a new one if you need an new Android feature or go DIY with 3rd party cooked rom this is despicable.
Fully agree with the resolutions. There is no need for 2k and above on mobile devices. These are just stunts most android device makers use to outsell other competitors about pointless specs which doesn't reflect everyday use of the device.
With the new iOS 8, iPhone 6, Pay, Touch ID, Watch these are fully integrated products which makes Apple way ahead of Samsung and the competitors. I believe Samsung is also an innovative company although they rip off they do have stuff that I like and just hope they concentrate on the important things and stop making those cheap rubbish adverts.
