It's almost everything that you are looking for, except for the physical keyboard. The Lumia line has some pretty good phones and you get all the basics of a modern smartphone (good cameras, email, browser, GPS, etc.) but the app store doesn't have a lot of apps to distract you.
My Lumia 735 does all the modern basics very well and everything I need in a phone. But the App store is like a ghost town so very little to distract you. It has some popular apps, but even then they not updated or poorly done to same ones on iOS/Droid.
I am coming from two years with a Blackberry Z10 myself and using WM10 now for 6 months has pleasantly made me a believer in it. It is simple, smooth and pretty well thought out. I am really surprised it doesn't gain more ground, but the world is all about APPS rather than the technical merits of the OS (otherwise BB10 would have become more popular).
The WM10 virtual keyboard is the best stock i've used and even beats the 3rd party ones i've tried on droid. It has awesome word prediction and built in swipe typing for those that prefer that. Cortana is VERY well done and again easily competes with Siri (I've actually had to whip out my phone a few times to quickly just find what my wife was asking for on her iPhone). Edge browser is fast and nimble (plus will be getting extensions soon I hope). Maps also is good enough. But best feature, to me, is how well WM10 ties into your Microsoft life; Office/Outlook plus Onedrive.
Just go through the settings to turn off any privacy stuff you may have concern with and it is a good modern phone for someone like me who has zero social media life other than texts. You can also get even a flagship phone used pretty cheap now as well. I am looking forward to the new Surface phone.
