Some worries & concerns:
- Nexus 6p build compared to iPhone, amount of glue on Nexus 6p in iFixit tear down worries me
- Quality of 3rd Party Applications in the Play Store (good alternatives to tweetbot & overcast for podcasts)
- Ads in applications, screenshots and youtube show people with ads in their applications; prefer to pay without ads
- Size, such a huge size difference from iPhone 5 to Nexus 6p
- How does Android age, the iPhone 5 has aged gracefully for me (first iPhone that I think aged well)
Excitement:
- fast charging
- dual front facing stereo speakers
- access to more opensource applications
- powerful automation applications
- ability to change app defaults (hopefully?, not sure never used Android)
- integration to a linux desktop
Unknown:
- fingerprint placement on back

Google hardware support is very good and generally better than other Android OEM's.
Fenix for Twitter is best Twitter client on the play store
Ads in applications - usually there are paid versions of apps or in-app purchase upgrades to remove them. I have no apps with adverts and will not use apps with them, if I use the app I'm willing to pay for it.
Size difference between 5 & 6P is considerable. You will either love it or hate it. Give yourself a week, Google have a 15 day returns policy if you find yourself unable to adjust
Android on nexus devices is safer bet for long term support. On most other devices android wise I wouldn't expect more than 18 months support or 1 major OS update and even then months and months after it has officially launched. You chose wisely to avoid that with a Nexus device. You should see longer term software support.
Fast charging is very handy. Though not the fastest - fast charger it's very good. 0-100 in around 90 mins
You will be able to change app defaults and easily.
Fingerprint reader on back will be subjective (like it / dislike it) but it is at least very accurate and super fast.
