Now that's just silly.
Why is it wrong to want everything that was great with BBOS and everything new that came with BB10? Isn't that progress? Does going to a "new" OS mean going back to scratch and ignoring what worked before? That's a recipe for failure. Why not do something that has been proven time and again to be successful: build upon past successes and make improvements? Most products develop that way -- in a linear, evolutionary way. BB10, on the other hand, seems to be going in a circular way with fanboys trying to argue that with a new OS comes a "re-do".
