FYI...We're talking about the iOS, not the desktop Mail.
It's particularly cool when someone in the body of an email message mentions something like >"Thursday" - data detectors intelligently understands that it means this week and will assist you in >creating an iCal entry.
I appreciate your opinion, but I just don't find that cool at all. On the contrary, it's annoying! E.g.:
I'm terribly ill, and on Thursday will stay home from work.
This prompts an iCal entry for Thursday? Come on! It either has to be much smarter, or it's just a nuisance.
The main issue is it should obviously be a user preference. Most features like that are optional, not required. Can you think of any reason not to have Mail Preference "Use smart links: Yes/No"? I can't.
