I recently moved to a retina display Mac, and so have had to give up the official Twitter application as I was having to strain my eyes to read the blurry text. Anyway, I'm now looking for a replacement client. What do you use and why? So far I have considered both Osfoora and Tweetbot. Osfoora is out of the running because of a bug with retina displays that has been outstanding since June, and Tweetbot is in my opinion just too expensive.
