Dear Cultured Code, you are history ...
I have been Cultured Code customer for over 2 years and used multiple their products: Things on OS-X, Things for iPad and iPhone on daily basis.
Not any more.
I am definitely giving up on Things and Cultured Code products.
The reason why is sheer frustration from long wait on usable synchronization between Things on Mac, iPad and iPhone. Something that have been discussed, promised, chewed over 2 years and that still does not work.
