My primary machine at home is a MacBook Pro.  Overall I really like it as my primary machine.  When I first got my MBP I used it almost exclusively to run Windows XP via BootCamp.  It wasn't until I tried using a beta of Parallels that promised BootCamp support that I ended up switching to Parallels and the wonder that is Coherence mode.  Over the last couple of months I've been doing mostly writing and/or work in TextMate so I've used XP via Parallels very little.  Lately I've had a couple of things come up that have me back in XP with VS.NET and some non book sample sized projects.  I'm finding it quite painful.  Most of my usual keyboard shortcuts don't work (althought I can get some to work by using the fn key), things seem painfully slow lately, and I'm not a happy camper.  I'm trying to figure out if I need to reconfigure my Parallels image, or if its time to switch back to BootCamp.
