Removing the RAM

2GB (two 1GB SO-DIMMs) of 1066MHz DDR3 SDRAM are included. Apple will upgrade the RAM to 4GB for an extra $150.

Apple claims this machine maxes out at 4GB RAM, but the Montevina chipset appears to support up to 8GB.

Shameless plug: You can upgrade your existing MacBook or MacBook Pro to 4 GB. We'll also be offering the RAM for the new Unibody machines in the near future.
