What is the advantage of Blackberry over iPhone and Android phones?

hi, as far as i know,some people here in my country wanted to have Blackberry phone because of the unlimited BBM and this BBM can only use to Blackberry phones,but i wish to have Blackberry phone but not qwerty type of keypads.

dear Well first of all i have one blackberry {the one with the touchscreen not sure what its really called} for work and i have a iphone for personal.A blackberry has one of the best keyboards{it does take some time to get used to it though} and my blackberry,i really love it.Sure there arent has many apps as lets say an iphone but it does have some good ones.Its a great work phone and i use it all the time.The screens kinda small to touch and everything but if you can get past that like i did then its a great phone.I cant say it is better or worse then a android or iphone they are quite different.

I don't think there's one single type of phone that fits everybody's needs... That being said, few differences pop in my head... First, battery life... Like many people, I have mixed group of people I work with... Some have android phones, some have iPhones, some have blackberry... Place I work for relies heavily on phones for communications... Any given day, we all go through few hours of talk time on our phone... People with androids & iPhones are constantly complaining about their phones dying... Android phones & iPhones don't have an option to change out the battery, at least not internally... I know there's a case for iPhone that has extended battery built into it... But that also adds bulk to the phone... On an average, I go through somewhere between 2,500 to 3,000 minutes of talk time in a month... I've used 3 different iPhones & one of the reasons I ditched them were because of this reason... Second, email system is independent of web based emails... I have email through aol... When I delete an email in aol website, with android & iPhones, it disappears from the phone as well... With blackberry, I can have a copy of an email on my phone without having to worry about it disappearing from my phone when I delete it in website... May be there's a way to make that happen with iPhones & androids too... Third... Memory... For the most part, it doesn't really affect day to day use... But with blackberry, there's an option to put memory card into the phone... I have close to 900 pictures on my phone for work reason... It just makes it easier for me to swap it back & forth from computer without having to worry about carrying a data cable all the time... Fourth, apps... I understand androids & iPhones have tons of apps available... I use 7... Blackberry does them just as good as all the other phones... I don't do games, music, TVs, on my phone... For me, it's not a toy... It's a tool... Don't get me wrong, they're all good phones & they all have their purpose & different people find different phones useful based on their needs... For what I use the phone for, I'll stick to blackberry...

The advantage from Blackberry is only it's BBM, other than that, It's no good... I'm using android phone and it's a lot fun... You can also use whatsapp (it can be use by Blackberry user, Iphone and Android user) or gosms (it's only for android phone) A lot of games and application in android phone... That's what i think :-)
