This MacBook "Core 2 Duo" 2.26 13-Inch (White Polycarbonate "Unibody" - Late 2009) unveiled a new "glossy white unibody" case design that uses polycarbonate rather than aluminum and has a "non-skid" rubberized bottom surface.
This model is configured with a 45 nm "Penryn" 2.26 GHz Intel "Core 2 Duo" processor (P7550) -- with two independent processor "cores" on a single silicon chip -- a 3 MB shared "on chip" level 2 cache, a 1066 MHz frontside bus, 8 GB of 1066 MHz DDR3 SDRAM (PC3-8500) installed in pairs (two 4 GB modules), a 250 GB Solid State (SSD) hard drive, and an 8X DL "SuperDrive".
