10 million iPhone users are a fertile source of research subjects for IBM.

IBM is seeding the Apple iPhone store with free applications so they can try out
experiments on the phone that gobbled up 17% of the market after little over one year.

One app, WritingPad, is all about easier data entry (faster typing) and another is designed
to sync multiple devices.

When Google's Android phone OS becomes prevalent (as it no doubt will) IBM will be
doing some research there as well.
