Share links, notes, and pictures between iPhone and Mac?
Solution 1:
Apple OSX Mountain Lion has been announced, it includes a few of the iOS apps on the mac desktop such as Notes, Game Center, reminders, twitter and message.

Solution 2:
The best solution I have found for quick and seamless transfer of clips, pictures and links is PasteBot.
Currently it works for WiFi sync, but in practice, my phone is always with me when I get home and I don't really need the data to get to the mac sooner than when I'm back home. I would expect them to try to extend the syncing to use the iCloud API announced but still in beta testing - but there's no promise it will work just like iMessage over the air using sync.
I don't use PasteBot to share links since I use pinboard.in and instapaper for that and they work so much better for me than getting the links over a clipboard. The announced Reading List sync between iOS and Safari on the desktop might also serve your needs.
Good luck - there are many options and hopefully you find one that works best for you.
Solution 3:
I agree iMessage is the best solution. For those that (for whatever reason, may not be able to use this) here is a solution for quick notes sync. I created a contact on my iPhone called "My Notes" and put what text I want on the notes section and it instantly syncs with Address Book on my mac. And at the desktop I do the reverse, I go to the same contact and add a note in the notes section and it syncs instantly.
Quick, no file to create/save/manually sync/whatever.
However, it's only for quick text notes, not photos/files/etc.
I thought it was cool ;) but iMessenger is more complete and now it's available... but hey, it's good to have choices.
