But that's not a pro-BlackBerry argument. There are Android phones with keyboards. Maybe they're terrible keyboards compared to a BB (I don't know), but an Android OEM could make an Android phone with an amazing keyboard if they wanted. That's not something exclusive to BlackBerries.
The only Android phones with keyboards these days tend to be underpowered, as most manufacturers try to make their high-end phones as thin as possible. While I certainly would prefer a physical keyboard, I can get by with an on-screen one.
