I think one of the most common things I've heard in reference to those with OS 4.5 is something along the lines of "I really hate that the beta drops network connectivity all the time, but I love the font too much to downgrade." Well, if you happen to want the font, actually named DejaVu, for your PC (or other machines that handle TrueType fonts), you can download it here:

OS 4.5 - 'BBAlpha Sans' Font for your computer
