Build Quality
The 8820 is an interesting addition to the Blackberry line-up but we have been disappointed with the battery life and the overall build quality of the device.
The Pearl feels solid, while the 8820 feels a bit cheap to the touch. RIM may want to consider an aluminium product or something like the stainless steel Nokia 8800 (if they can keep the weight down) for the top end of the product line.
The review is correct about the "nuances" of the wifi settings and the applications' ability to exploit the high speed access - that's if you can get the device connected in the first place.
It is a good first try and is likely that it could improve with software updates.
