Poll: Are you writing apps for just one form factor?

Do you write apps for the tablet or phone only or for the lowest common denominator, or do you adapt to the form factor? Take this quick poll.

In the last year or so, the introduction of the iPad has given mobile application developers another form factor to consider; the larger size of tablets really does open new possibilities! At the same time, phones, such as the Droid Bionic, are starting to get more flexible. When you write an application, do you aim for "lowest common denominator," or do you optimize your UI for either a tablet or a phone device? Or maybe you've created UIs that adapt to the device in use?
