BlackBerry devices are not for everyone, as you have found. Some people are comfortable with and accept the functionality of the devices, and some want something more and different.
For instance, I love my BlackBerry, but hate the browser. However, I accept it since I don't want/need another device. I don't like iPhones for typing, I am not comfortable with Android devices, and I've never used Nokia.
I'd suggest getting the device (if you can now) that works for what you need/want.
