Better than most

Pros:
- I like Twitterific for its ability to sync tweet markers between multiple devices.
- Not built on Adobe AIR.

Cons:
- No ability to permanently turn off spelling auto-correct. It will deactivate for a while, and then turn on again-- maybe after restart? Id really like the app to remember my preference.
- No upload to Twitter picture service.
- No ability to have 2 windows from 2 twitter accounts into a single window, a la Tweetdeck.
- Confusing error message when trying to retweet a locked account. (Took a while to figure this one out.)
