I would, if it wasn't such a big commitment just to try it.
The problem is that you spend a bunch of money and then you're pretty much stuck with it for 2 or 3 years (or you pay a lot up front to buy the phone outright, or you pay a lot later to leave your contract). If it works out well, then it's a good deal. If it doesn't work out well, then it isn't (especially since I'm very happy with my Android phone).

I will upgrade my Playbook to see how that goes.
