Probably the best product review I've ever read.

What the title said:

The SSD Anthology: Understanding SSDs and New Drives from OCZ by Anand Lal Shimpi

The 64GB version of the OCZ Vertex is currently only $170 after rebate at Newegg, so barring anything major, I think I'll be buying that, or maybe the Summit, along with Windows 7 when it's released later this year.
