Thanks so much for taking pains and posting an indepth analysis. i am sorry to respond late as i just read all those Blackberry related posts (my mistake as i never thought that someone would take pains for BB that has already lost market share, so i just read the last page posts on this thread and missed your significant analysis). just yesterday same time i purchased Z10 ( though you mentioned the lack of FM radio etc. but i had some tight budget ).
..mm.. i really wanted something more that just "it sucks" :-p. anyways it is your personal opinion and i respect that, i guess your opinion is based on your other awesome phones. and i guess you are true as it nowadays seems to be a personal matter.
coming back to phone...
my last device was nokia 808, i purchased it only for thing that 41MP camera ( i considered the phone free.. ) and was happy with it. it had almost everything that a simple user needs. Also with the same price i could purchase a single camera which would be almost as good as nokia 808's camera. so the phone was almost free.. i compared it with the same priced camera's and did not found much of a difference. nokia's market share has surely plumetted but that does not mean that a particular phone ( nokia 808 ) is bad. i tried to get a second 808 yet again but could not, so then started googling/surfing, etc.
i was in two minds iphone 4s or blackberry z10 after actually using them for a couple of minutes. but again iphone 4s was out of my budget. again surfed and found a youtube video where in a guy showed blackberry z10 being as fast as iphone 4s. also ergonomically it is as good as iphone 4s ( to me ). so finally bought it.
to me the best part is speed. it responds very fast, also you could just open anything without much of a hassle. YES IT IS VERY VERY FAST.. that compensates for any cons whatsoever. to type messages on it is buttersmooth.
just loving it..
Speaking of market shares and all that stuff. it depends on hell of a stuff and sometimes the better product might get beaten like anything, just my view. also it helps people like us to pick stuff which might be better but is not costly because it does not have market share. :-p
sorry for the verbose reply.
John ... you working ?
