How much HD space to allocate?

[lu0s3r322]

I've got a Macbook Pro coming as some of you know with a 120GB hard drive.

I'm planning to install Windows on it but I don't know which version and how much. With Vista, it takes up about 5GB just on its own, which is far more than Windows XP, but it is better.

I'm planning to use Windows for some games, one being Flight Simulator X which I think takes up 14GB.

How much should I allocate?

i use the RTM version and only allocated 15gb and vista alone took about 9gb.

your best bet is to allocate at least 20gb if you intend to d anything in vista like download and install apps.
