Nice article Chris, thanks!
I too appreciate the subtle changes in the new OS which make my working life easier.
There are a few annoying issues which I'm sure will be addressed in the next update in the coming couple of weeks.
For example... It's great to be able to search for a word like 'Howard' in spotlight, click on a pdf and have the first occurence of Howard be highlighted -- but Preview blows the text too big at the moment, and I have to press Zoom Out a few times to see the entire page.
Your mention of DEVONthink reminds me that it was a previous article written by you about this software which encouraged me to check it out and buy it. What a great application! Thanks again!
