No, but it isn't because of the OS. It is the form factor and keyboard. I don't find the Treo keyboard easy to type on and thus tend to avoid responding to emails. This kind of defeats the point of having a keyboard in the first place. I found carrying a treo uncomfortable too as it is just not a comfortable size to me. I would say the same about the HP HW6510. Surprisingly, the Sprint PPC 6700 is easier to carry and I think easier to use overall. I'm sure there are other people that feel just the opposite. No one has more ergonomic keyboards than BB, in my opinion. The new screen also helps and now they have a real processor too.
