Windows 8 Login Oddity

Lots of stories flying around about Windows 8 since the Consumer Preview was made publicly available for download; people hate it, people love it, it's the end of Microsoft, etc. This one is bit more practical though, and it will be interesting to find out the answer; the WSJ's Amit Agarwal found there is apparently a 15-character limit to logon passwords in the Preview version. He is unsure if it's just a UI bug, or an actual limit - although the latter would seem kind of odd.
