mac mini is better
i bought a laptop and it gets hot and its just not as durable as a desktop
fans will kick in after watching 10 min of flash video(or anything flash probably),
Only buy laptop if you move around a lot, in college, work, coffee shops and more. If you mainly work from your desktop then no use, specially now that the iPad will be out for browsing is good so mac mini+ipad= $1100 that is about just $100 more than the cheapest apple laptop.
