There are tons of glitches in iMovie, iDVD, and iPhoto. (They just fixed them in the 10.4.5 update.) I think it was a premature release for iLife overall.
iWeb kind of let me down with it's ability to customize the templates, but you can kind of "trick it" to do what you want. The pages are written in bloated code with frames, which is very slow to load. For some reason large text is converted to an image when uploaded. Here's my site created completely with iWeb.
Digital Memories
Over all I think it's a decent program, but not for *serious* web developers. The only reason I used it for my website is that I wanted something easy to update and change, and with GoLive on GoDaddy.com, it's not that easy.
I think it's a decent purchase, but if you're content with iLife '05 and don't want to spend the $, you're not missing much. However, if you need a pretty simple website creation program, and not looking for a ton of customization, then iWeb might be right for you. :mac:
