Just bought a brand new Q5, in 2016
So let me first start off by saying I have used all mobile OS'es, Been into Android in the early days, and then switched to a Z10 when they first came out. After that someone offered me $600 for it even though I wasn't trying to sell it, and I kinda needed the money at the time, but it was a mistake and I regret selling it, but after that I landed a good job where my work provided me with Samsung Phones, and I had to use them. I did have a Playbook for a short time and loved it, but it quit working (my fault due to leaving it in a hot car, not blaming BB at all for this)
All good and dandy using a Samsung S5, but I really missed my Z10 and BB, and just recently they allowed me to use my own device. So I just bought a brand new Q5 from amazon, and let me tell you, I am so glad I am back, and the new 10.3.2 is better than what I remember which was 10.1 I think.
The reason I got the Q5 was that I am absolutely tired of carrying around large 5+in devices in my pocket, on top of the fact that in a work place you need to have a decent case not damage your phone which makes them even bigger!. The Q5 is perfect to fit in my pocket, and I wasn't totally sure how it was going to preform by today's standards, and paying only $117 new from amazon I didn't want to spend that much.
I don't use a ton of apps, but the ones I do use I was able to find in Blackberry World, and I know I can side load if I need anything out of the ordinary. But the thing I love about BB10 is how everything is integrated and just seems to flow with everything! Blend is freaking amazing, and I love how BB in general actually gives you instructions if something is jacked up! unlike android or apple which leaves you in the dark. IMO anyways.
I know most people wouldn't by a phone made 3+yrs ago, but if it was anything like I remember I never had 1 issue with the Z10, so I made a gamble and holy crap am I happy! I know it sounds like I am getting paid to say all this but I assure you I am not, I just want people to know BB really is that good if you aren't all "App happy" lol
