From the Intel press release (items of interest in bold)
I wonder if OSX will offer TRIM support for SSD's?

Also, an explanation as to why Apple had previously avoided the Intel SSD's but now may support them...
Exciting times!
The Intel X25-M on 34nm flash memory is drop-in compatible with the current 50nm version and will continue to be drop-in compatible to replace existing hard disk drives (HDDs).
Compared to its previous 50nm version, the new Intel X25-M offers improved latency and faster random write Input/Output Operations Per Second (IOPS). Specifically, Intel's new SSD provides a 25 percent reduction in latency, for quicker access to data, operating at 65-microsecond latency compared to approximately 4,000 microseconds for an HDD.
Random write performance increases twofold, further separating the X25-M from other competing SSDs. By delivering up to 6,600 4KB write IOPS and up to 35,000 read IOPS, the X25-M continues to set the bar for SSDs, while leapfrogging HDDs which only operate at several hundred IOPS. This provides for markedly faster system and application responsiveness. These improvements in latency and IOPS not only benefit desktop and notebook users, but also server and workstation users, as they utilize Intel's cost-effective, yet performance-oriented, MLC SSDs for enterprise computing.
New channel prices for the X25-M 80GB are $225 for quantities up to 1,000 units (a 60 percent reduction from the original introduction price of $595 a year ago). The 160GB version is $440 (down from $945 at introduction) for quantities up to 1,000 units. The X25-M comes in a standard 2.5-inch form factor. The X18-M, in a 1.8-inch form factor, will begin shipping on 34nm later in the quarter.
Drop-in compatible with SATA-based HDDs and all operating systems, the X25-M will also support Microsoft Windows 7 when it becomes available. At that time, Intel plans to deliver a firmware update to allow support of the Windows 7 Trim command, along with an end user tool, to allow users to optimize the performance of their SSD on Windows XP and Vista operating systems.

A little known fact about the original X25-M was that its controller wasnt Halogen-free. Because Intel used Halogens in the first controller, companies that had strict environmental restrictions (e.g. Apple) wouldnt touch the drives.
The new drive has a new controller and it is Halogen free. For Apple to glance over the X25-M in its mobile lineup now would be a serious mistake.
Exciting times!
