I came from an iPhone 4 and the reason I changed was to get out of Apple's ecosystem.
What opened my eyes for Android was that I bought a Chinese Android tabled and I was overwhelmed with the things I could do with it. Nobody forced you to run one specific software and you could overclock, underclock etc.
Then I realized which kind of prison Apple has put their customers in, and since it was time for a new phone (had my i4 since Q2 2011 and it was becoming laggy) I wanted something awesome.
When I first purchased my iPhone, it could handle virtually EVERY game, but as it grew older it started to lag even with simple games and the whole user experience wasn't as pleasant as before.
So when I was looking for a new phone, I had some requirements:
- Good battery life
- Display Density same as or over my old iPhone
- Good hardware
I really don't use my camera that much, so that wasn't a problem for me at all but it was nice to know it had a 13MP shooter with OIS.
My choices were boiled down to either the Note 3, LG G2 or Nexus 5. I disliked the XPERIA Z1 - no idea why.
I wanted the Note mainly because of the stylus and the split-screen, but it's size and price were a huge turnoff. The Note 3 was about $200 more than G2.
The LG had a nice screen, good size (albeit a tad too big since my fingers are relatively small), great battery life and a smooth UI - and it was cheap too!
The Nexus 5 was the phone I was wanting the very most prior to it's release - Stock android, timely updates and blazing fast. In Denmark, however, you can only get the 16 gb version and many reviews claimed that the battery wasn't really big enough. The Nexus 5 was priced equally to the LG G2.
I was quite unsure about the hardware buttons being placed on the back and the fragility of the phone, but I still purchased it. I haven't regret it (and I won't be doing that anytime soon) and it continues to amaze me.
I was uncertain about the "future-proof"-ment of the Snapdragon 800, but when I saw the announcement of the Snapdragon 805, I figured it wouldn't be that much of an upgrade to the Snapdragon 800 and that the next-gen 64-bit processors wouldn't come before late '14. I plan on keeping my G2 for another two or three years and despite the "slow" updates, I am seriously considering LG as my next phone as well.
