I've never owned a Mac before, but I've been so impressed with my iPhone over the last 10 months or so that I'm considering buying a Mac Mini. I assume that I'll need to pick up an Apple Mouse & Keyboard, but do I have to buy an Apple Display? Will my existing Dell monitor work with a Mac? I assume that it would, but I figured that I'd check first. The monitor makes the difference between spending over $599 or spending over $1198! Thanks!
