I am pretty sure by this point we have realized that it will come down to personal preference, anything otehr than android is wrong, but the sheep wont understand that so lets not start a fight.
here is a fun little experience I have had recently. Girlfriends mother has had a BB since like the first models because it was company issued, so she was very used to the ecosystem.
when her personal upgrad rolled around she chose an S4 mini. still dont know why do that, but hey not my problem.
around the same time the company phones were changed over to iphone, so right now she has with her an iphone 5s and an s4 mini.
chatted to her last night and she hates the iphone, she says its like flogging a dead horse, apps take longer to open, webpages related to work render slower, emails take forever to open and the fact that she needs to fiddle around to find the apps she uses most annoys the k*k out of her.
on the other hand her s4 mini is all set up, with custom ringtones and widgets and she loves it, everything is where she wants it and changing the locations of icons is a major plus for her.
and before everyone harps on about how "you need to get used to using your iphone" or "if you don't set it up properly it wont work for you" just remember she got the phones within days, I don't know what phone was first but what I do know is that for her going from BB to a smartphone Android was more intuitive.
then as for WP, I have said this a few times here, we all complained about how windows messed up for at least the last 15 years, we all hate on internet explorer, and blue screens of death is no ones favourite way to go. knowing that please explain to me how it is logical that now that you have all this choice available for your phone you choose to be tortured by a windows 8 look and feel in your pocket?
then the reason android is the best for me:
root,
custom ROM,
custom launcher,
Titanium backup,
CPU controls like over and underclocking.
widgets on my screens.
Pie controls, yes this is not something that is standard with android, but I cannot live without it anymore.
also android tabs after honeycomb are better than idevices, because the iOS limitations put you in a cage, but you are so happy at the decorations in the cage you don't even see the bars.
