I just bought an ipad 2 because of how affordable it is. I was wondering if anyone knows the ppi for the ipad 2 compared to the iphone 3gs? i borrowedd my friends iphone 3gs to see if there were display difference and we can really see that the ipad 2 has a sharper display. It wasnt a huge difference but the ipad 2 does seem crisper. It may be that we are seeing things so i just wanted to see if anyone knows their ppi. thanks.
