As a CrackBerry enthusiast, I too frequent the site and there is * a lot* of mixed reviews about the Priv. The fanbase seems to be split into two camps: they love it or they despise it (for a slew of reasons). I've never owned the Priv, so unfortunately I can't give you any tangible solutions to your quandary... But what I will point out is that forums can be deceptive. A lot of people will post about issues to look for help; and will do that more often than posting things like praise reports/positive reviews of the device. Some people seem to focus more on posting about tech issues/concerns/questions than actual positive facets of the device; which can then make other posters/people who are doing research think that that device is inferior. Just something to consider.
I can't remember if I was on CrackBerry or Android Central (it was probably CrackBerry - yes, it was, actually); and there was a forum thread with a link to an article about a Priv review. Reading it actually made me understand how an "old school" BB enthusiast could go from being iffy about the device to really enjoying it (i.e., you hear people saying, "I don't like it/learned to like it," but they don't tell you how they went about it/how the process occurred; and this reviewer was pretty honest).
I've heard that the keyboard is not the same as other BB keyboards in the past; however, I've also heard that it's still quite good. Also, yes, the camera seems to be a selling feature. There are a few really good reviews of the Priv, and there are a lot of people who do like it. It's disappointing that the Priv has gotten a lot of flack; as I personally think that BB was being brilliant in combining its hardware/sick keyboard with Android's OS... But I digress.
My suggestion to you (my two-cents' worth LOOL) is to go to your carrier and try a Priv in the store. See if they will actually let you give one a test drive. Tell them about your concerns. I definitely get what you mean - I LOVED my Q10 and my 9780, and still miss the physical keyboard... It's hard to give up!
Also, the mods at CrackBerry are always very knowledgeable about the newest stuff - maybe send one of them a PM and ask about the Priv.
