I've used but never owned 'droids.
I've owned seven BlackBerry handsets over the years, going way back to when they looked like a desktop calculator.
I had a dally with an HTC HD7 earlier this year - quite liked it, but like the original iPhone, it's lack of features I take for granted was a huge problem for me (me, personally - others may not be so bothered about a lack of cut and paste, for example). I also found it uncomfortably large. Now my elderly neihbour, to whom I gave it, loves the fact that he can read everything on it and it has big tiles he can mash with his fingers.
I've had an iPhone 3GS and now have a 4. I switched to iPhones because I got tired of the poor build quality of my BB's. When the annual handset renewal comes up in January, I'll no doubt look to get the 4S.
I also didn't like the fact that on a BlackBerry, to sync more than just email (e.g. calendars), I needed an additional server component (BES) whereas the others just connect and work.
And really, for me, that's the crux of it. I like how it looks and I like how it feels but at the end of the day it's just a phone and for me, it works as well as I need.
It isn't a fashion statement or a statement of wealth and privilege. It might be seen as a mindless following and I will admit that I didn't really put any thought into it beyond "BlackBerry's seem to be ridiculously unreliable so what else should I try?".
If you want to hate me for my choice of a mobile telephone/car/computer then I feel quite sorry for you. I certainly don't judge a person by the _things_ they own.
I feel no need to defend my choice - if you don't like it for reasons x, y and z that's fine. It's your decision. I respect that.
But...it's just a thing and in 100 years it, me and these silly extremist point of view arguments won't matter a jot.
