No curverd, smaller screen. qwerty is no problem with small screen, i have motodroid 4 and that has good qwerty for write.
I use it because no qwerty good phone is on market.
today is no problem with the RAM and storage in small size.
If I first read about your phone spec, great CPU, RAM, qwerty I am happy, but later I read the size my big happy is change to smaller happy...
