Well, as a recent switcher (from WP to Android) I was tempted to say NO, but the reality is different.
Even though I'm enjoying a custom rom equipped Nexus 6 that is:
- blazing fast
- offers me real multitasking
- offers me a real hangouts client (that do NOT need to be run every 5 days in order to re-arm the push notification system, and can actually know when the message have been read on another device etc..)
- a descent mapping service when traveling in some countries like JAPAN (no covered AT ALL by Here service)
- endless possibilities of interface customization
- the infinite list of great games, and by great games I don't mean gameloft freemium crap, I'm talking about - for example - Baldur's Gate 2 incredible port, Braveland, Crowntakers, all the Kairosoft games...etc
STILL
I miss the Lumia camera SO MUCH it almost hurts... For real, every time I take a picture I want to cry.
I mean, coming from a 930, I'm just so disapointed at how crappy the HDR+ function of the google camera is rendering.. Even on a GS6 it looks.. fake, you've got no control over the hdr exposure, you've got a heavy interface that will lag at the moment you need instantaneity, you've got a strange photo album organization, kind of messy...
Well, ok I'm just focusing on the camera/picture features here but hey.. it's almost enough to make me buy a cityman/talkman very soon.
And hey... when you're out of memory on your internal sd, you think you can just switch everything on your android external ? Yeah they like make you think you can, it even looks like you did it. But you did not. You just move the apk executable package file on the external, but all the app data (for example maps in a gps applications, environnement in a 3d games) will REMAIN on the internal memory. Forever. A real nightmare.
So now I don't even remember the initial Yes/No question.. Had to scroll up a bit.
Okay, would I buy another Microsoft Mobile ? Yep, I would. And I'm pretty sure I would rage for a few day at the missing apps from android, but I'm also sure I would feel relaxed to know that I have a clean, regularly updated, smooth, harmonized system with a DAMN DECENT CAMERA APP ON IT.
