So it's coming out on the 20th US time? I have a 2GHz Intel Core 2 Duo and btw, a memory of 1 GB 667 MHz DDR2 SDRAM Apple says this is enough, but I know next to nothing about processors. Is this on the slow end I would guess? Installing a new OS near the minimum specs possible can leave one with a pretty miserable response time, if memory* serves.
