This would be killer, if you could launch the iphone app and be taken back to the last tweet you saw on the desktop app, these amazing apps would then be perfect.

Having Tweetie integration between the iPhone and Mac application would be fabulous! I read my tweets on both platforms and keeping them in sync would make for an amazing experience (not to mention provide people with more incentive to purchase both apps). While you're at it, why not allow syncing between multiple Mac clients. That way people who use Tweetie both at home and at work can keep the two clients in sync.

Love it.

Being able to read a bunch of tweets on the iPhone and *not* having to scroll through all of them again when I get home would be amazing.

This just makes sense. I'm guessing one big "con" for the developer is that he'd probably need his own servers as an intermediary between the two clients. Still, it would make Tweetie a million times more awesome.

It's possible that tweetie iPhone and tweetie Mac could tweet some "hidden" tweet that shows the last updated location on the timeline, then the programs would just hide this tweet.

This would be a really awesome feature. I'm close to trashing my Tweetie desktop app, only because there's no decent sync between the two.
