iPad software is cheap

Here is an upside to iPad which one may not think about: a lot of software, like image processing and writing software, has versions for iPad which is almost as full-featured as the desktop version, but costs less than 20% of it!
 Example: Final Draft scriptwriting: $250 for desktop, Final Draft Writer, for iPad: $20. Pretty much same feature set.
The only reason for such a great price difference is that Apple pressured app developers into super-low prices, so it’s a true deal.

 And an iPad with an external keyboard is easily less weight than a laptop, and can do most of the work. I think it’s a great thing for a lot of work which does not require a complex interface.
