Bought the 10" I-pad 30 GB for use at home for my wife some 3 years ago.
Pros:
The build quality is exceptionally good,
The display is the best I have ever seen.
Sound quality is excellent, One can use the std headset with 3.5 mm jack.
Camera(Front & Back) very good, Photo & Video recording: very good.
Cons:
A bit heavy to hold in one hand for long (off course, due to its excellent build quality).
Does not support many Video formats.
Communication to PC is only through ITunes.
No slot for additional memory.
The unit was dropped 7 times in last 3 years. But has remained intact and working as good as new.
