It is very important to have a nice multi language support. If not for the interface, the dictionary support for as many languages as possible is critical. As I live in Bulgaria, we use Cyrillic, and the support for the Opentype subsets and other options is really important, if you want to produce a high quality documents. For me, the language support in Designer and Photo is a bit limited for non latin based languages, especially for Cyrillic. And the Cyrillic itself has a variations, e.g. Bulgarian is not the same as Russian, or Serbian and Macedonian. I can live with this in these programs, but for Publisher it will be a deal breaker.
