Has there been an announcement regarding ATA TRIM support? It's about time.

No announcements, but according to this screen shot it looks like it's there. http://www.macstories.net/news/os-x-lion-adds-trim-support-f...

Displaying the fact that an SSD supports TRIM does not prove that HFS+ uses TRIM, but it's a good sign.

MBA Late 2010 (i.e. SSD only) and I have TRIM support listed in Sys Profiler.

Interesting - I'm on a Late 2010 MBA (11 inch) and mine says TRIM Support: No

Odd. My 11" (128GB model) says yes.
