Which Hard Drive?

[hapachris]

I'm just one click away of buying me the new iMac (20') , but there's one thing left of which I'm not sure: whether I should get the hard drive with 250GB or with 500GB.
I want to use it as my main Windows XP machine as well. So should I get the 500GB one, because there are gonna be two operating systems installed or are 250GB enough?
I do have an external 250GB hard drive.

Any advices?

It varies from person to person, and it depends on your use.

I'm getting a MBP once Rev B comes out, and I know for certain that 120GB will be plenty for me to run both a Windows and Mac partition. But that's my use. Some other people probably can't survive on anything less than 250GB.

is it possible to swap hard drives in the imac or would that like void the warranty? What size hd does it use anyway?
