There are some pictures of the ipad version on the website:

Hard to see what improvements they made, except that they're using the BG2 engine (as Baldur's Gate Trilogy and others do).
If I had an ipad or similar I might be interested, but I hope there are going to be some bigger and better improvements. Otherwise, why would I pay for something that the modding community provides for free?
