Can I reply your question with another question?
What do you miss the most on android? Because I am seriously thinking of jumping, but I live in Brazil and cellphones here are REALLY expensive. Right now, I have a 640 XL, looking forward for the 950 XL which still doesn't sell around here. I'm also a carrier client for a very long time, which usually means huge discounts. Right now I could upgrade to a G4 (which I'm inclined not to because I'm a large screen guy) or a Note Edge (which I'm inclined not to because it's very dated and probably won't get 6.0 or 7.0 features) which price around the same with my carrier discount.
When I studied the possibility of a switch, there were a few major holdbacks:
-I really like the jumplist feautre in W10M. Makes thing easier to track down on just about any app. I find Android quite messy whenever I'm trying to find anything. Nothings is alfabetically organized, settings change name every other phone and I usually have the hardest of times trying to find just about anything in an android phone. I know that I'll get used to it, but having a steep learning curve makes a platform unapealling for me.
-I'm really into the skype+messaging integration. I love interactive notifications and I know they don't work like that on Android
-I have an 50GB+ music collection on my OneDrive I stream via Groove. Streaming services don't have all the music I listen to (Yes, I'm that alternative), so having my music collection in Onedrive is kind of a major deal and I know Groove on android is one of the few apps that is significantly worse.
-I'm a productivity guy and I'm all in on MS services. I have three Office 365 accounts (personal, office and college) and not being able to manage my e-mail, calendar and using office apps is totally a deal breaker, bc I usually complement powerpoints or edit spreadsheets on the go on my W10M
-I'm in love with Cortana. I like the fact she has personality, unlike Google Now. I also like how she truly learns from me, such has understanding when and where I work, the kind of news I like to read and most of all location based reminders, which are amazing for me since I have irregular schedueles and a really crappy memory
I know that sounds like settling, but the app gap really isn't major for me. Instagram and Twitter were just about the only two daily apps that I wanted updated. Well, that and WhatsApp and Messenger, but I've all but replaced them with Skype+Messaging (since most of the people I talk to mostly are on W10 too). I ditched all news apps for the amazing RSS Reader NewsFlow, so I don't miss news reading apps either. That kinda sums up my use of an smartphone: News Reading, Listening to music, exchanging message and being productive (Wunderlist+Outlook+Slack = <3).
That said, what do you see in W10M that you haven't found on android? Do you think I can get all of those things done in android?
