There's a lot of "Made for Windows"/"Made for Mac" debating going back and forth here.
I have to agree, this application doesn't have a Mac "feel". It doesn't flaunt any of the feeling, ease of use, etc. that we've come to expect from Mac.
Today we can video chat from our phones. We can design websites in the blink of an eye that are aesthetically pleasing and fully functional. We can create virtually anything. Photoshop designs are outstanding driven by power beyond power.
There really is no reason this can't improve. Everything can improve. I'd love to see this turn into something that works as easily as something like RapidWeaver, iWork, iLife, etc.
