Now I am using iPhone 7 plus and Windows notebook. And at work I am using windows PC. I do on them:
1) e-mails (I am working in the sphere of science and also do a lot of admin, that is why I have hundreds emails everyday and I have to respond on them very quickly). I use Spark on iPhone and Outlook on my PC and laptop, sometimes Web interface on PC and laptop
2) MS office full version, acrobat D.C. full version (PC and Laptop), scan docs (iPhone)
3) Calls
4) SMS, MMS (sometimes I do mailing via SMS to 250 people at one time)
5) Viber, WhatsApp, FaceBook
6) Bank apps (but I can do bank operations in web also)
7) Safari on iPhone and Chrome and Opera on Laptop and PC (searching in internet)
Will I do the same on one device - HP E X3?
