I really like the interface and all the options for customization, but the app crashes about 5 times a day on my iPad and iPhone and then gives me a "sorry about that" window when I log back on. Sometimes this happens in the middle of typing an email which is not recoverable. I dont know if this is a unique experience because everyone else seems to have nothing bad to say- but this is definitely not a flawless app as some people have described.
