The BlackBerry A10 is a bigger screen replacement of the current Z10 flagship. Specs that leaked earlier this month tell us it will pack a 5" AMOLED display with 720p resolution and a dual-core Krait processor at 1.7GHz (up from 1.5GHz, but it's the same chipset). The battery has seen a massive 1,000mAh bump to 2,800mAh, but other than that it's mostly the same as the Z10.
A new video (again from Taiwan) plus a whole bunch of photos give a quick hardware tour of a working BlackBerry A10. As can be expected, it's taller and wider than a Z10 (which has a 4.2" screen). The back panel seems to made of Motorola RAZR-like Kevlar material and is removable.
While the battery is not accessible, there are some helpful labels under there, which confirm the specs from the leaked slide. The A10 is 9.4mm thick, a hair thicker than the Z10, and has a metal frame under the back cover.
The BlackBerry A10 was running BB OS 10.2, but there are no immediately noticeable changes to the UI over 10.1. The unit bears an AT&T logo on its back.
Unfortunately, there's still no info on when the BlackBerry A10 will launch.

Nobody does email like blackberry. It is a bit shy of the specs by Samsung and Apple. Little more juice won't hurt
I guess that is a personal thing. It works great for me when I'm on the go. I don't have to screw around with the battery door or even turn off the phone, which is inevitable when switching battery. Just plug it in.
Battery packs are great when you're semi-stationary but not when you're on the go.
