80GB: How big of a Windows partition?

I'm going to install Windows on my new MBP. It only has an 80GB HD, so I'm wondering how large I should make the Windows partition. I plan to run MS Visual Studio, MS SQL Server, Visio, Dreamweaver, and Photoshop in Windows. I don't plan on playing any games.

How large do you think? 20GB? I don't want my Mac to be struggling for storage space since I'll most likely use OSX 75% of the time.

Parallels with a 100 GB "partition"

I opted for Parallels instead of BootCamp because I didn't want to have to reboot to switch into Win XP. So, I installed Paralles on my Wintel iMac with a 100 GB partition. It's not actually a partition, just a file that looks like a file system to XP. Works great! I actually do .Net development on my Mac. I run Live Meeting and Outlook for work, and all operates flawlessly. I can easily share the clipboard and files between the OS X and XP sides of the machine. I have two monitors, and I use one for OS X and the other for XP. I cannot say how great this setup is.

I'll second that Parallels recommendation. Why reboot to run Windows if you can run it at nearly native speed inside a window while already running OSX? You can't do any serious 3D work or games, obviously, but for being able to run XP and OSX at the same time, well... you just have to try it and once you do, there's simply no turning back. :)

I have a 20" iMac, another 20.1" LCD; on the left is the iMac running OSX, on the right is XP running full screen inside Parallels inside OSX running at nearly native speed - it's actually faster under Parallels than it is on a 1.6 GHz Pentium-M Dell laptop I have, go figure.

Parallels simply rocks, 'nuff said.

I'd do 40GB windows 40GB mac. I use photoshop on mac and all my pictures as well as a few games and hardly use any space. On my windows side with gaming tho, I used all 20GB. I would do 30GB if not 40GB for windows. What do you plan on doing via mac side? email/surf/pictures? you will have plenty and an external HD is $100 or cheaper for 250GB
