i've started at my company as only person with a Lumia phone(at that time 920) ,thereafter many phones, 1020,830,640,650,950 and now 950 XL . I've converted so much people to windows phone ive lost count, now over 40 persons at workplace have Lumias, my assistant recently upgraded his 640 to 950 over xmas holidays, i'm to order 650 for another staff who even had Lumia 625 for quite sometime now, but cracked his screen the other day for that phone.
