If it were best in every other aspect, I would tolerate Java. But I agree that the UI is ugly (I like one thing though - that it allows you to view the change log as it was available with the old Live Mesh Beta - it was an amazing feature for troubleshooting and for my confidence in the product).
BTW Amazon just launched Glacier storage for data backup which costs just $1 per 100GB per month. Wow.
Glacier? Glacier is a poor name for any product or company unless you're in the ice business.
