Its hard to say. The iPad is brilliant, but may be more limited than a laptop for certain uses, such as complex spreadsheets.
I have an iPad with Ancestry's iPad version of my tree on it. ?I also
have the Gedview app on the Ipad. ?The latter seems easier to use and
edit "on the hoof".
I like the iPad for its long battery life and great portability when
compared with a laptop. ?However, remember you will need to email your
self reports pics etc, or sync the Ipad with your home based computer
to get info in / out of the Ipad.

I hope this helps.
