Im using the transformer to write this.
Pros:
Decent battery life(especially with the keyboard)
Key board has usb port.
Pad has internal memory, and micro sd card.
Keyboard has full sd card slot.
Pad has micro hdmi out.
Plenty of games and apps from android market.
Can use mouse pad and touch with keyboard connected.
Live wallpapers.
due to extra battery in keyboard, you can charge keyboard whilst using the pad elsewhere.
Cons:
Web browser freezes every now and then, have to press wait.
Limited number of web tabs to open.
If trying to type with on screen keyboard, if you drag fingures a little, swype kicks in.
Speakers not super loud.
Youtube sometimes takes forever to load. Last update made it better, but i find, you have to close backgroud programmes.
