Is blackberry good ?

Is blackberry fast enough than other phones ? I want to buy one..Which is better, Android or Blackberry ? I want optical track-pad as in blackberry and fast enough..

being Android Apps Developer i will suggest you to go for Android phone and use its SDK for gr8 fun

I dont like any of them.. After working so deep with Android, I start to dislike it. So many bugs.

Then Ajay, which is best phone according to you ?

I am clueless about what is good/bad. Its totally one's opinion. I myself still use my N8 symbian. Pretty happy with it. good hardware.. slow but good responsive OS (annoys some times)

galaxy S3 is not bad in terms of usability. iPhone is same thing over and over.. they want you to spend your money thats it. BB is ok.. i never spent too much time with it. But just for reading emails why woud one get this phone?

from what i have observed is that android devices needs a lot of resources(ram n processor speed) to run smoothly compared to other OSes. but it does provide tons of features too. in BB devices u ll probably find it to have least specs n feature for entertainment comparatively. iphone has gr8 hardware + gr8 OS but a bit less features compared to android n quite costly. windows phones have started to expand into d market so u can expect gr8 features from it but it might take some time. so in the end its abt what u want from it. personally i wud prefer an iphone but too costly for for me so m just waiting for windows 8 cells to launch. rest is upto u. do lets us know what u buy
