Before the Playbook, Monza all the way. Now that I have a Playbook, I'm leaning more toward the 9900 as the Playbook gives me a lot of screen real estate. I plan on checking out the Monza when available though and seeing how good the virtual keyboard is before deciding. If it is good then I'll probably go with the Monza.
of course this is your decision to make...however, i'd wait for the bold touch because i dont care much for touch screens that lack a physical keyboard
