Me too; I copied some archive folders to a PC hard drive so I could see the effect as the raw cache was building.
I'm still using a steam driven P4 PC so I see big benefits in this situation. 
I get a polite message if I'm too soon in opening the editor which explains that that the first time you do this it takes a little more time because the cache is building.
It's very nice that I can now comfortably check e-mail from the forum while caching is taking place, or open Firefox, or any other program for that matter. Like Fred says, I'm in control again.

Now, does this mean I can put off buying a new PC for even longer   :-\

The new Chrome skin is a good one; I'd used Cyber 2010 before but this one is very clean, easy to read with no distractions when looking at images.

Mike said "Initial release", that implies there'll be more  goodies to come, nice.
Thanks Mike.
