I liked my Sidekick, and the keyboard was pretty good. But honestly I've been pretty happy with how software keyboards have evolved, and I'm pretty sure physical buttons would just slow me down at this point.

However, one thing I'll continue missing from the Sidekick are the gaming controls. It had a horrible d-pad and buttons but at least it had them. They've been forced out of smartphones in the name of shaving off bezels and making the aspect ratio taller (eww). Give me a phone with a tiny d-pad and buttons please
