I'm looking into purchasing a 1.67ghz powerbook with a cracked screen. Right now there is a huge jump in the price for a Hi Res LCD panel over a low res panel. Like $200 difference. I'm trying to figure out if the low-res panel will work with the computer, or if I need to get a hi-res one. Along with this, I'm wondering if 15" Apple Studio Displays have the same LCD panel in them that powerbooks do because that would be a great secret as they are going for around $90 when LCD panels are around $180. Any ideas?
