I only upgraded because it was free and I kept the stratosphere for my kids to play with. Nice big screen, didn't freeze on me. I enjoyed it. We now call it the "fun phone" because as long as you have wifi, it downloads and plays games fine.
Love the ease of the keyboard, wish they wouldn't have done away with this model. cases are cheap in price. phone is well built. no user issues, takes a fall pretty well. easy to navigate use. good storage space too
