Okay, so I'm wondering how I should connect my 20" monitor to my 13" uMBP that I'll have in a week. Mostly, it's a VGA vs. DVI question. My monitor uses both, as most modern ones do, but right now I only have a VGA cable. So with that, I plan to either get either a VGA or DVI to Mini-Display Port adapter. So would there be a difference between VGA and DVI? And after that, where's the best place to buy an adapter? Surely there's gotta be a cheaper option than a $30 one from Apple.
