if you have not tried BB ever....its right time to get to do it....if u r in Lahore you can get a used BB9780 in decent condition for around 16-17K it has best value for money and is a premium product (only if you can bear a device already used by unknown person) i can describe SOME pros and cons of it:
PROS:
nothing beats BB in signal strength
nothing beats BB in call quality ( the sound quality received/transmitted ) even u can tweak it by enhancing bass/treble etc
nothing beats BB in terms of battery life as it is always online
u can drop it countless times and it goes on (build quality and durability is excellent)....u actually have to hit it hard on wall to get rid of it (i did it a month back to get a new BB)
BB OS is very stable...and if u never used it before u can keep it exploring at least for a month till to get to know all features....as a rule of thumb u can utilize a thing to full potential if you know it completely.
you can have 10 push email configured on it (required BB plan)
you are always online on MSN,GOOGLE,Twitter,Whatsapp,Viber,yahoo through numbuzz,Skype through IM+ facebook, facebook messenger and off course BBM (required BB Plan)
BB is automatically taking back up of your important data and saving it on servers (through BB Protect if u opt to use it) you can wipe ur device, ring it, send message to it, block it, see it on map through BB Protect.
you can connect it to laptop and use high speed internet unlimited (required BB plan)
multimedia capabilities are quite good ,5MP camera video camera, music library voice notes sound recorder.
holster changes its alert setting automatically.
and you can use TAPATALK on it...
CONS:
email is only in text format
internet tethering is not fully functional (requries BB desktop software to use intrnet)
OS a bit difficult to understand foe newbies.
security is way too much beefed up.
you will start hating NOKIA...
Once u get into BB...u cant live without it...i have iphone, Android but still cannot let go BB even after 8 years...
