RAMINF  I have gone through four different FTP clients (not counting the ones built into DreamWeaver and Espresso). But for copying files quickly to my server, I always go back to using ExpanDrive. Having the server be an extension of the filesystem makes it so you don't have to think about all the extra steps needed to move files back and forth. Being able to directly edit my server config files in TextEdit or add a line to a remote CSS file using CSSEdit is beyond awesome.

Haven't had any problems across any of the different hosting sites I use. Heartily recommended.

RAMINF  I've used Export2QT from the same developer to convert Hitachi VRO files to Quicktime. This will make for a nice upgrade.

RAMINF  Nice! Be curious if it introduces too much anti-aliasing, especially with HD video.

RAMINF  I've used external third-party monitoring services like Service Uptime to monitor my websites and email servers in the past. What looks to be nice about Simon is that I can run it from inside the firewall to monitor MySQL, Samba and things that aren't out on the public internet.
