Hi guys,
Hope you guys can brief me on some of the things that I might missed out of having a iPad.

I plan to buy one, still deciding on the size required. Don't think will go for the 3G model...
My usage:
1. Let my son play game
2. Let my wife watch RMVB movie and also online streaming.
3. Might need to store some cartoons for long journey trips.
...I think I will jail break it as well.

So what iPad cannot do to fulfill my usage above? Can my external hard drive work as a storage for iPad?

Really appreciate the feedback.
