Can use to see if it is worth it. As foscooter said, there should be some new ones out soon. How much better than the C300, well Im hoping.
I'm looking at it from this standpoint, it should drop the Sata II SSDs price. I would be looking at say a 256 gig Sata II for my laptop vs upgrading my Intel G2 (SATA II). Once I've upgradded my two Laptops to larger capacity SSDs, THEN I'll think about improving the performace on my desktop ( moving to a SATA 6 SSD)
