Ok, I'll start. Have Z10, was looking at Q10 or Q5 couldn't wait and don't want to give up bigger screen. Virtual keyboard is about good as torch, but bold keyboard still better; unless you send 100's (literraly) texts per day touch screen better. Only truck dispatcher and air traffic control need Q10. Can run all the android apps, have kik, instagram, skype, etc. plus bb security, integrated email, hub, multitasking, and qnx micro kernel os. This means I can search 2 or 3 things at a time for example, becasuse it is like search process and not app. Many times I open one email, and search app another. Can send photo to fb, or email from camera app; take pictures from picture app, etc. everything is integrated all together. Hard to explain, easier to demonstrate. Better to use than PC, but pc much more powerful.
