The 650 is the best phone i have ever owned and here's why.

I have had my new Lumina 650 for 5 days now which replaced my very trustworthy but a tad to small Lumia 435.
Never had any complaints about my 435 therefore how can I say anything bad about the 650 other than its to thin and to light.
I miss the physical home and back button and the chunkiness of my 435.
The 650 is fast and vibrant and quite happy with it.

I would advise people to buy a good solid case as its only a matter of time before you drop it and finish it.
Really wish I could buy a Windows phone with a Panasonic Tough Book like build.
 
Sorry that happened. I suggest you buy a screen protector now for it. The adhesive will help stabilize the crack and help to prevent the cracks from growing. Good luck.
