Migrating iPhone app to iPad

Hi,

we have a featured productivity app for travelers, which manages your expenses at home and abroad.

Porting the game to the iPad is a logical step, however I'm not sure which alternative should be better:
- universal app - doing a favor to our loyal customers
- standalone iPad app (HD version)

While I tend to rather go for the universal app approach, the second choice has also it's advantages (being able to set a different price for the HD version, the app will show up as new, etc.).

Any comment or suggestion would be highly appreciated - eventually honored with a promo code (see http://travel.nyisztorkaroly.org/?page_id=68 for details).

Finally here are the draft iPad UIs (wip):

My thoughts are to create a universal version. That way your existing customers get to reap some of the benefits.

The only point in making a separate HD version is if you are going to add a whole bunch of iPad only features that make use of the extra screen real estate.

Just my 2 cents worth.
