I've never used a Blackberry but it was much more efficient for me to input text (an essential task for a communication device!) on non-iPhone-style phones with physical buttons.
Nothing useful to add except, god I miss my Bold 9700. Every time I slip on this stupid touchscreen keyboard and make a stupid typo on this stupid phone I howl inwardly and wish pain and endless torment upon everyone who took us down this path away from light and goodness. Grumble grumble
The fun part for me is that an old dumb phone could replace, like, 50% of my smartphone usage, if I could use Telegram on it. We even still have 2G networks with no plans to shut them down. So, a J2ME Telegram client has been on my list of potential future projects for quite some time.
