I like my Katana, but my biggest complaint is the ringtones aren't loud enough. Especially the ones you download from Sprint, they're almost like a whisper. Also it doesn't support ANY ringtone formats except for the stupid QCP (purevoice) tones that sounds like a scratchy old AM radio, or
MIDI.
I'm not sure about the Razr because I haven't used one, but on the Katana the keypad is completely flat, there is no contour or texture to help you feel your way around the keys (I used to be really good at texting without looking at the keypad, now I have to watch where my fingers are going).
I haven't tried out the Razr but I'm told the ringtones are plenty loud... and I would hope that it supports more than QCP and
MIDI. All the ringtones that came with the Katana are pretty stupid... other than that, it's a great phone and gets awesome reception in places where my other Sprint phones would be searching for service (like deep inside large buildings). Let us know what you decide.
