I Know so many People who jailbreak their iPad with the sole intention to Be able to download commecial apps for free.
I think jailbreaking itself is Not Bad if you Need to free up your iPad, but come on! for what the apps cost, and for the amount that each individual needs, it is surely affordable to Pay for the work that the programmers have invested in their product.
Would Be nice to Know other People's views on this matter.
Have a good Day
