Snow Leopard and Windows 7 on MacBook White I have an MacBook White, will it support Snow Leopard and Windows 7 (via BootCamp).

Are there any softwares/apps (in particular) that won't work after I install Snow Leopard and windows7.

MacBook Specifications

2.0GHz Intel Core 2 Duo Processor

2GB DDR2 SDRAM

13.3-inch TFT screen

NVIDIA GeForce 9400M graphics processor with 256MB of DDR2 SDRAM shared with Main Memory

NOTE: I know it's old system, but can't help it.
If you are installing windows via bootcamp the two systems will have exclusive use of all resources. You won't have any restrictions on the apps you install other than your existing restrictions of disk space, ram or your graphics processor. 

I would suggest upgrading your machine to 4GB of ram as both Snow Leopard and windows 7 like at least 4GB of ram.
