Can the phone with a USB otg cable power a hardrive (not just a flash drive)?

Whatsapp is integrated in the Hub?

How does the keyboard feel, comparable to the passport or to the classic?

Is priority hub there?

Sorry buddy I have no way of checking that.No. The Hub is a mess.It is the fantastic keyboard we know and love. Most like the Q10 I think. It naturally feels small compared to the Passport but then it is smaller. It is easy to type on and in just over a week I have had it I constantly pop the keyboard out to reply to messages.No. I never used it in BB10 so I do not know exactly what it should do but I cannot see any mention of Priority in the Hub.
