yea, i know -- the acrylic displays are OLD. but they are cheap and still look SO nice. i can pick up either of these sizes for less than a $100 from my buddy. i've heard that the 20" has a crisper display. it's also about a year newer than the 23" HD. anyone have some advice? the price difference isn't much, maybe about $25. i already have an ADC-to-DVI adapter, so it won't be a problem hooking up to my MBP.
