Make a decent phone, decent price, slide out physical keyboard, long battery life and goddam headphone jack and there you go, Try to imitate the iphone and they will fail.
Apart from the price *and the battery life*, you're describing the Priv exactly.
I busted my phone a couple of months back (low-slung car and closing doors, don't ask), so I figured I'd take a venture on the Priv, since I like pretty much everything about BB except the paucity of apps when compared to the Android ecosystem.
I had it for approximately 24 hours, then brought it back (and thanked goodness my provider had a 'love it' guarantee on new phones!). The battery life was...less than optimal. I unplugged it in the morning the day after I received it (approximately 7:30 AM) and by 10:00 the battery was at 40%. That's AM, not PM. Yes, I was pretty much using it constantly over those 2.5 hours, trying out some features, but mostly just reading DYAC and other casual web browsing: no video streaming or other typically battery-intensive tasks. Sorry, if I wanted to have to charge my phone twice or three times a day, I'll go back to 2002.
That being said, I had absolutely no complaints with the OS or any other features: the keyboard was easy to use, keyboard shortcuts were great, etc. The phone was maybe a bit off-balance with the keyboard extended, but with practice it wouldn't have been an issue. It seemed responsive and snappy, easy to configure and find things. There were a lot of things that I liked quite a lot about the phone...but I just couldn't handle the battery life. My new S7 may be full of Samsung bloatware, but at least she lasts 2 to 3 days between charges, even if I decide to spend a couple of hours reading DYAC...
