Dropbox doesn’t work properly on Lion yet! Based on this Dropbox Forum thread, the Droboxers are working hard on an update, but without much success yet. The thread is full of nasty-sounding, up-to-the-minute bug reports from users who have installed the public beta. Dropbox is mission-critical for me, as you might gather from my blog post singing its praises. So until the new Dropbox client gets out of beta, I am unable to upgrade to OS X Lion.

Updated 9/9/2011: Dropbox finally released their Lion-compatible update a couple of weeks ago, just in time for me to install Lion before going on vacation. It’s been working well.

Updated 10/13/2011: Apple released version 10.7.2 of Lion yesterday. Now I finally feel comfortable installing Lion on my family’s other computers. In particular, it looks like Apple has fixed some of the nasty bugs in Safari.
