I don't know. I know, or knew, of people who had a weekday BlackBerry and weekend BlackBerry and just moved the SIM back and forth. FYI with BlackBerry ID there is a limit of something like 15 or 15 per year on the number of times you can swap the ID to another handset. Look it up. I'm not sure it applies if you are swapping back and forth as opposed to another different handset each time.
Me, I have gotten use to the touch screen. I don't miss the keyboard as much as I was afraid I would. I don't know what the Q10 would give me that I would use. I think your decision is a personal one that depends on you. Different strokes.
