iPhone 5 Vs Note 2

Earlier I made some posts (this and this) , (So both of us are getting new phones)

Yesterday , an interesting thing happend which i didn't expect.We went to store to look at iPhone accessories but surprisingly he purchased a Note 2 (Gray color) there.

We really liked the device so much (Also Size isn't problem for him because he always used phone with 2 hands right from moment he used touch screen phones) And my hands are big enough to handle it and i don't really care about one hand or two hand operation.Note 2 surprisingly fits decently in pockets (which we didn't expect) I learnt a lesson that until you see a device and use it , we cannot judge it easily.

He upgraded from Galaxy S2 and I will upgrade from Nokia 5800 Xpress Music.So i have to decide which device to get.

I liked Note 2 but App quality is not quite good though and also being iOS user for nearly 2 years , Android feels like another world (because whole new store for apps and also design of Android apps is quite different from iOS) , but I am sure i will get easily used to it.But I am not dropping WP , I would also like opinions for Lumia 920/HTC 8X

On one hand , getting iPhone 5 will not change anything because I am existing iOS user but on other hand if i get Android phone , (iPad + Android phone) combo gives me best of both worlds whereas WP gives me unique experience and fresh feel.Cannot decide which one fits better

I am a long term user (as u can see that I am upgrading from a 4.5 year old Nokia 5800 Xpress Music phone) , So which one fits better ? (I don't have any faith in WP as long term device tbh but who knows)

This decision also reflects my purchase whether to get Mac Mini or not , If i get Note or WP , I will drop the purchase of Mac because i recently realized that OS X does't play well with non-apple devices.
