I am a recent convert (since Mar 07) and run Windows Vista Home Premium on my MacBook with Bootcamp.
It really depends on the type of applications you intend to use with Vista. I use Vista primarily because of Word, Excel and Powerpoint which I need for work. I did not want to spend money on Mac Office, while Neo Office did not work so well for me because it typically involved some reformatting when files were opened in MS Office (esp. for complicated spreadsheets and powerpoint slides).
I have also installed some other programs on Vista like itunes (so that I can listen to music while I'm working), quicktime, acrobat reader and nokia pc suite. Internet access on Vista while running Office at the same time is without noticeable delays, except in you tube where the streaming of videos is excrutiating long. In general, apart from MS Office, everything that I do is done in Mac OS X.
If you intend to run Bootcamp with Vista and Mac OS X then I suggest to get more RAM and a larger harddisk. I bought my MacBook off the shelf (1 MB RAM and 80 GB hard disk) and in no time I had upgraded it to 2 MB RAM and 160 GB hard disk.
Good Luck.
