finally played with a q10 tonight and to be honest, I wasn't impressed. I am a HUGE blackberry keyboard fan. I held on to my 9900 as long as possible before i decided to try out the z10 until the q10 came out.
either the z10 is so great that it converted me to the dark side of the touch screen, or the q10 is garbage. I didn't like the keyboard, i didn't like the screen ratio to the unit size, i didnt like how the OS has a squished feeling after you're coming from a z10.
i swore i'd never get a non-qwerty physical keyboard phone, but i think i'll stick with my z10. hopefully "10s of millions" of other users like it.
